+       op( X ) = X   or   op( X ) = X',
+
+    alpha and beta are scalars, and A, B and C are matrices, with op( A )
+    an m by k matrix,  op( B )  a  k by n matrix and  C an m by n matrix.
+
+    Parameters
+    ==========
+
+    TRANSA - CHARACTER*1.
+             On entry, TRANSA specifies the form of op( A ) to be used in
+             the matrix multiplication as follows:
+
+                TRANSA = 'N' or 'n',  op( A ) = A.
+
+                TRANSA = 'T' or 't',  op( A ) = A'.
+
+                TRANSA = 'C' or 'c',  op( A ) = A'.
+
+             Unchanged on exit.
+
+    TRANSB - CHARACTER*1.
+             On entry, TRANSB specifies the form of op( B ) to be used in
+             the matrix multiplication as follows:
+
+                TRANSB = 'N' or 'n',  op( B ) = B.
+
+                TRANSB = 'T' or 't',  op( B ) = B'.
+
+                TRANSB = 'C' or 'c',  op( B ) = B'.
+
+             Unchanged on exit.
+
+    M      - INTEGER.
+             On entry,  M  specifies  the number  of rows  of the  matrix
+             op( A )  and of the  matrix  C.  M  must  be at least  zero.
+             Unchanged on exit.
+
+    N      - INTEGER.
+             On entry,  N  specifies the number  of columns of the matrix
+             op( B ) and the number of columns of the matrix C. N must be
+             at least zero.

+
+    ALPHA  - REAL            .
+             On entry, ALPHA specifies the scalar alpha.
+             Unchanged on exit.
+
+    A      - REAL             array of DIMENSION ( LDA, ka ), where ka is
+             k  when  TRANSA = 'N' or 'n',  and is  m  otherwise.
+             Before entry with  TRANSA = 'N' or 'n',  the leading  m by k
+             part of the array  A  must contain the matrix  A,  otherwise
+             the leading  k by m  part of the array  A  must contain  the
+             matrix A.
+             Unchanged on exit.
+
+    LDA    - INTEGER.
+             On entry, LDA specifies the first dimension of A as declared
+             in the calling (sub) program. When  TRANSA = 'N' or 'n' then
+             LDA must be at least  max( 1, m ), otherwise  LDA must be at
+             least  max( 1, k ).
+             Unchanged on exit.
+
+    B      - REAL             array of DIMENSION ( LDB, kb ), where kb is

+             matrix B.
+             Unchanged on exit.
+
+    LDB    - INTEGER.
+             On entry, LDB specifies the first dimension of B as declared
+             in the calling (sub) program. When  TRANSB = 'N' or 'n' then
+             LDB must be at least  max( 1, k ), otherwise  LDB must be at
+             least  max( 1, n ).
+             Unchanged on exit.
+
+    BETA   - REAL            .
+             On entry,  BETA  specifies the scalar  beta.  When  BETA  is
+             supplied as zero then C need not be set on input.
+             Unchanged on exit.
+
+    C      - REAL             array of DIMENSION ( LDC, n ).
+             Before entry, the leading  m by n  part of the array  C must
+             contain the matrix  C,  except when  beta  is zero, in which
+             case C need not be set on entry.
+             On exit, the array  C  is overwritten by the  m by n  matrix
+             ( alpha*op( A )*op( B ) + beta*C ).
+
+    LDC    - INTEGER.
+             On entry, LDC specifies the first dimension of C as declared
+             in  the  calling  (sub)  program.   LDC  must  be  at  least

+    Purpose
+    =======
+
+    SGEMV  performs one of the matrix-vector operations
+
+       y := alpha*A*x + beta*y,   or   y := alpha*A'*x + beta*y,
+
+    where alpha and beta are scalars, x and y are vectors and A is an
+    m by n matrix.
+
+    Parameters
+    ==========
+
+    TRANS  - CHARACTER*1.
+             On entry, TRANS specifies the operation to be performed as
+             follows:
+
+                TRANS = 'N' or 'n'   y := alpha*A*x + beta*y.
+
+                TRANS = 'T' or 't'   y := alpha*A'*x + beta*y.
+
+                TRANS = 'C' or 'c'   y := alpha*A'*x + beta*y.
+
+             Unchanged on exit.
+
+    M      - INTEGER.
+             On entry, M specifies the number of rows of the matrix A.
+             M must be at least zero.
+             Unchanged on exit.
+
+    N      - INTEGER.
+             On entry, N specifies the number of columns of the matrix A.
+             N must be at least zero.
+             Unchanged on exit.
+
+    ALPHA  - REAL            .
+             On entry, ALPHA specifies the scalar alpha.
+             Unchanged on exit.
+
+    A      - REAL             array of DIMENSION ( LDA, n ).
+             Before entry, the leading m by n part of the array A must
+             contain the matrix of coefficients.
+             Unchanged on exit.
+
+    LDA    - INTEGER.
+             On entry, LDA specifies the first dimension of A as declared
+             in the calling (sub) program. LDA must be at least
+             max( 1, m ).
+             Unchanged on exit.
+
+    X      - REAL             array of DIMENSION at least
+             ( 1 + ( n - 1 )*abs( INCX ) ) when TRANS = 'N' or 'n'
+             and at least
+             ( 1 + ( m - 1 )*abs( INCX ) ) otherwise.
+             Before entry, the incremented array X must contain the
+             vector x.
+             Unchanged on exit.
+
+    INCX   - INTEGER.
+             On entry, INCX specifies the increment for the elements of
+             X. INCX must not be zero.
+             Unchanged on exit.
+
+    BETA   - REAL            .
+             On entry, BETA specifies the scalar beta. When BETA is
+             supplied as zero then Y need not be set on input.
+             Unchanged on exit.
+
+    Y      - REAL             array of DIMENSION at least
+             ( 1 + ( m - 1 )*abs( INCY ) ) when TRANS = 'N' or 'n'
+             and at least
+             ( 1 + ( n - 1 )*abs( INCY ) ) otherwise.
+             Before entry with BETA non-zero, the incremented array Y
+             must contain the vector y. On exit, Y is overwritten by the
+             updated vector y.
+
+    INCY   - INTEGER.
+             On entry, INCY specifies the increment for the elements of
+             Y. INCY must not be zero.
+             Unchanged on exit.

+    Purpose
+    =======
+
+    STRSM  solves one of the matrix equations
+
+       op( A )*X = alpha*B,   or   X*op( A ) = alpha*B,
+
+    where alpha is a scalar, X and B are m by n matrices, A is a unit, or
+    non-unit,  upper or lower triangular matrix  and  op( A )  is one  of
+
+       op( A ) = A   or   op( A ) = A'.
+
+    The matrix X is overwritten on B.
+
+    Parameters
+    ==========
+
+    SIDE   - CHARACTER*1.
+             On entry, SIDE specifies whether op( A ) appears on the left
+             or right of X as follows:
+
+                SIDE = 'L' or 'l'   op( A )*X = alpha*B.
+
+                SIDE = 'R' or 'r'   X*op( A ) = alpha*B.
+
+             Unchanged on exit.
+
+    UPLO   - CHARACTER*1.
+             On entry, UPLO specifies whether the matrix A is an upper or
+             lower triangular matrix as follows:
+
+                UPLO = 'U' or 'u'   A is an upper triangular matrix.
+
+                UPLO = 'L' or 'l'   A is a lower triangular matrix.
+
+             Unchanged on exit.
+
+    TRANSA - CHARACTER*1.
+             On entry, TRANSA specifies the form of op( A ) to be used in
+             the matrix multiplication as follows:
+
+                TRANSA = 'N' or 'n'   op( A ) = A.
+
+                TRANSA = 'T' or 't'   op( A ) = A'.
+
+                TRANSA = 'C' or 'c'   op( A ) = A'.
+
+             Unchanged on exit.
+
+    DIAG   - CHARACTER*1.
+             On entry, DIAG specifies whether or not A is unit triangular
+             as follows:
+
+                DIAG = 'U' or 'u'   A is assumed to be unit triangular.
+
+                DIAG = 'N' or 'n'   A is not assumed to be unit
+                                    triangular.
+
+             Unchanged on exit.
+
+    M      - INTEGER.
+             On entry, M specifies the number of rows of B. M must be at
+             least zero.
+             Unchanged on exit.
+
+    N      - INTEGER.
+             On entry, N specifies the number of columns of B.  N must be
+             at least zero.
+             Unchanged on exit.
+
+    ALPHA  - REAL            .
+             On entry,  ALPHA specifies the scalar  alpha. When  alpha is
+             zero then  A is not referenced and  B need not be set before
+             entry.
+             Unchanged on exit.
+
+    A      - REAL             array of DIMENSION ( LDA, k ), where k is m
+             when  SIDE = 'L' or 'l'  and is  n  when  SIDE = 'R' or 'r'.
+             Before entry  with  UPLO = 'U' or 'u',  the  leading  k by k
+             upper triangular part of the array  A must contain the upper
+             triangular matrix  and the strictly lower triangular part of
+             A is not referenced.
+             Before entry  with  UPLO = 'L' or 'l',  the  leading  k by k
+             lower triangular part of the array  A must contain the lower
+             triangular matrix  and the strictly upper triangular part of
+             A is not referenced.
+             Note that when  DIAG = 'U' or 'u',  the diagonal elements of
+             A  are not referenced either,  but are assumed to be  unity.
+             Unchanged on exit.
+
+    LDA    - INTEGER.
+             On entry, LDA specifies the first dimension of A as declared
+             in the calling (sub) program.  When  SIDE = 'L' or 'l'  then
+             LDA  must be at least  max( 1, m ),  when  SIDE = 'R' or 'r'
+             then LDA must be at least max( 1, n ).
+             Unchanged on exit.
+
+    B      - REAL             array of DIMENSION ( LDB, n ).
+             Before entry,  the leading  m by n part of the array  B must
+             contain  the  right-hand  side  matrix  B,  and  on exit  is
+             overwritten by the solution matrix  X.
+
+    LDB    - INTEGER.
+             On entry, LDB specifies the first dimension of B as declared
+             in  the  calling  (sub)  program.   LDB  must  be  at  least
+             max( 1, m ).
+             Unchanged on exit.

+
+
+    Purpose
+    =======
+
+    XERBLA  is an error handler for the LAPACK routines.
+    It is called by an LAPACK routine if an input parameter has an
+    invalid value.  A message is printed and execution stops.
+
+    Installers may consider modifying the STOP statement in order to
+    call system-specific exception-handling facilities.
+
+    Arguments
+    =========
+
+    SRNAME  (input) CHARACTER*6
+            The name of the routine which called XERBLA.
+
+    INFO    (input) INTEGER
+            The position of the invalid parameter in the parameter list
+            of the calling routine.

+ * HISTORY
+ *
+ * 10-Sep-1998 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University
+ *             Changed strcasecmp() call in cmp_name() to strcmp_nocase() call.
+ *
+ * 15-Jul-1997    M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University
+ *         Added required arguments handling.
+ *
+ * 07-Dec-96    M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University
+ *         Created, based on Eric's implementation.  Basically, combined several
+ *        functions into one, eliminated validation, and simplified the interface.

+
+/****************************************************************
+ * This is dtoa.c by David M. Gay, downloaded from
+ * http://www.netlib.org/fp/dtoa.c on April 15, 2009 and modified for
+ * inclusion into the Python core by Mark E. T. Dickinson and Eric V. Smith.
+ * It was taken from Python distribution then and imported into sphinxbase.
+ * Python version is preferred due to cleanups, though original
+ * version at netlib is still maintained.
+ *
+ * Please remember to check http://www.netlib.org/fp regularly for bugfixes and updates.
+ *
+ * The major modifications from Gay's original code are as follows:
+ *
+ *  0. The original code has been specialized to Sphinxbase's needs by removing
+ *     many of the #ifdef'd sections.  In particular, code to support VAX and
+ *     IBM floating-point formats, hex NaNs, hex floats, locale-aware
+ *     treatment of the decimal point, and setting of the inexact flag have
+ *     been removed.
+ *
+ *  1. We use cdk_calloc and ckd_free in place of malloc and free.
+ *
+ *  2. The public functions strtod, dtoa and freedtoa all now have
+ *     a sb_ prefix.
+ *
+ *  3. Instead of assuming that malloc always succeeds, we thread
+ *     malloc failures through the code.  The functions
+ *
+ *     Balloc, multadd, s2b, i2b, mult, pow5mult, lshift, diff, d2b
+ *
+ *     of return type *Bigint all return NULL to indicate a malloc failure.
+ *     Similarly, rv_alloc and nrv_alloc (return type char *) return NULL on
+ *     failure.  bigcomp now has return type int (it used to be void) and
+ *     returns -1 on failure and 0 otherwise.  sb_dtoa returns NULL
+ *     on failure.  sb_strtod indicates failure due to malloc failure
+ *     by returning -1.0, setting errno=ENOMEM and *se to s00.
+ *
+ *  4. The static variable dtoa_result has been removed.  Callers of
+ *     sb_dtoa are expected to call sb_freedtoa to free the memory allocated 
+ *     by sb_dtoa.
+ *
+ *  5. The code has been reformatted to better fit with C style.
+ *
+ *  6. A bug in the memory allocation has been fixed: to avoid FREEing memory
+ *     that hasn't been MALLOC'ed, private_mem should only be used when k <=
+ *     Kmax.
+ *
+ *  7. sb_strtod has been modified so that it doesn't accept strings with
+ *     leading whitespace.
+ *
+ ***************************************************************/
+
+/* Please send bug reports for the original dtoa.c code to David M. Gay (dmg
+ * at acm dot org, with " at " changed at "@" and " dot " changed to ".").
+ */
+
+/* On a machine with IEEE extended-precision registers, it is
+ * necessary to specify double-precision (53-bit) rounding precision
+ * before invoking strtod or dtoa.  If the machine uses (the equivalent
+ * of) Intel 80x87 arithmetic, the call
+ *      _control87(PC_53, MCW_PC);
+ * does this with many compilers.  Whether this or another call is
+ * appropriate depends on the compiler; for this to work, it may be
+ * necessary to #include "float.h" or another system-dependent header
+ * file.
+ */
+
+/* strtod for IEEE-, VAX-, and IBM-arithmetic machines.
+ *
+ * This strtod returns a nearest machine number to the input decimal
+ * string (or sets errno to ERANGE).  With IEEE arithmetic, ties are
+ * broken by the IEEE round-even rule.  Otherwise ties are broken by
+ * biased rounding (add half and chop).
+ *
+ * Inspired loosely by William D. Clinger's paper "How to Read Floating
+ * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *
+ *      1. We only require IEEE, IBM, or VAX double-precision
+ *              arithmetic (not IEEE double-extended).
+ *      2. We get by with floating-point arithmetic in a case that
+ *              Clinger missed -- when we're computing d * 10^n
+ *              for a small integer d and the integer n is not too
+ *              much larger than 22 (the maximum integer k for which
+ *              we can represent 10^k exactly), we may be able to
+ *              compute (d*10^k) * 10^(e-k) with just one roundoff.
+ *      3. Rather than a bit-at-a-time adjustment of the binary
+ *              result in the hard case, we use floating-point
+ *              arithmetic to determine the adjustment to within
+ *              one bit; only in really hard cases do we need to
+ *              compute a second residual.
+ *      4. Because of 3., we don't need a large table of powers of 10
+ *              for ten-to-e (just some small tables, e.g. of 10^k
+ *              for 0 <= k <= 22).

+   with more than STRTOD_DIGLIM digits.  It's called once an initial
+   estimate for the double corresponding to the input string has
+   already been obtained by the code in sb_strtod.
+
+   The bigcomp function is only called after sb_strtod has found a
+   double value rv such that either rv or rv + 1ulp represents the
+   correctly rounded value corresponding to the original string.  It
+   determines which of these two values is the correct one by
+   computing the decimal digits of rv + 0.5ulp and comparing them with
+   the corresponding digits of s0.
+
+   In the following, write dv for the absolute value of the number represented
+   by the input string.
+
+   Inputs:
+
+     s0 points to the first significant digit of the input string.
+
+     rv is a (possibly scaled) estimate for the closest double value to the
+        value represented by the original input to sb_strtod.  If
+        bc->scale is nonzero, then rv/2^(bc->scale) is the approximation to
+        the input value.
+
+     bc is a struct containing information gathered during the parsing and
+        estimation steps of sb_strtod.  Description of fields follows:
+
+        bc->e0 gives the exponent of the input value, such that dv = (integer
+           given by the bd->nd digits of s0) * 10**e0
+
+        bc->nd gives the total number of significant digits of s0.  It will
+           be at least 1.
+
+        bc->nd0 gives the number of significant digits of s0 before the
+           decimal separator.  If there's no decimal separator, bc->nd0 ==
+           bc->nd.
+
+        bc->scale is the value used to scale rv to avoid doing arithmetic with
+           subnormal values.  It's either 0 or 2*P (=106).
+
+   Outputs:
+
+     On successful exit, rv/2^(bc->scale) is the closest double to dv.
+
+     Returns 0 on success, -1 on failure (e.g., due to a failed malloc call). */

+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 112-126].
+ *
+ * Modifications:
+ *      1. Rather than iterating, we use a simple numeric overestimate
+ *         to determine k = floor(log10(d)).  We scale relevant
+ *         quantities using O(log2(k)) rather than O(k) multiplications.
+ *      2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *         try to generate digits strictly left to right.  Instead, we
+ *         compute with fewer bits and propagate the carry if necessary
+ *         when rounding the final digit up.  This is often faster.
+ *      3. Under the assumption that input will be rounded nearest,
+ *         mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *         That is, we allow equality in stopping tests when the
+ *         round-nearest rule will give the same floating-point value
+ *         as would satisfaction of the stopping test with strict
+ *         inequality.
+ *      4. We remove common factors of powers of 2 from relevant
+ *         quantities.
+ *      5. When converting floating-point integers less than 1e16,
+ *         we use floating-point arithmetic rather than resorting
+ *         to multiple-precision integers.
+ *      6. When asked to produce fewer than 15 digits, we first try
+ *         to get by with floating-point arithmetic; we resort to
+ *         multiple-precision integer arithmetic only if we cannot
+ *         guarantee that the floating-point calculation has given
+ *         the correctly rounded result.  For k requested digits and
+ *         "uniformly" distributed input, the probability is
+ *         something like 10^(k-15) that we must resort to the Long
+ *         calculation.

+ *
+ * Revision 1.6  2005/05/24 00:00:45  archan

+ *
+ * Revision 1.5  2005/05/11 07:01:38  archan
+ * Added comments on the usage of the current implementation of hash tables.
+ *
+ * Revision 1.4  2005/05/03 04:09:11  archan
+ * Implemented the heart of word copy search. For every ci-phone, every word end, a tree will be allocated to preserve its pathscore.  This is different from 3.5 or below, only the best score for a particular ci-phone, regardless of the word-ends will be preserved at every frame.  The graph propagation will not collect unused word tree at this point. srch_WST_propagate_wd_lv2 is also as the most stupid in the century.  But well, after all, everything needs a start.  I will then really get the results from the search and see how it looks.

+    -- LAPACK auxiliary routine (version 3.0) --
+       Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
+       Courant Institute, Argonne National Lab, and Rice University
+       June 30, 1999
+
+
+    Purpose
+    =======
+
+    ILAENV is called from the LAPACK routines to choose problem-dependent
+    parameters for the local environment.  See ISPEC for a description of
+    the parameters.
+
+    This version provides a set of parameters which should give good,
+    but not optimal, performance on many of the currently available
+    computers.  Users are encouraged to modify this subroutine to set
+    the tuning parameters for their particular machine using the option
+    and problem size information in the arguments.
+
+    This routine will not function correctly if it is converted to all
+    lower case.  Converting it to all upper case is allowed.
+
+    Arguments
+    =========
+
+    ISPEC   (input) INTEGER
+            Specifies the parameter to be returned as the value of
+            ILAENV.
+            = 1: the optimal blocksize; if this value is 1, an unblocked
+                 algorithm will give the best performance.
+            = 2: the minimum block size for which the block routine
+                 should be used; if the usable block size is less than
+                 this value, an unblocked routine should be used.
+            = 3: the crossover point (in a block routine, for N less
+                 than this value, an unblocked routine should be used)
+            = 4: the number of shifts, used in the nonsymmetric
+                 eigenvalue routines
+            = 5: the minimum column dimension for blocking to be used;
+                 rectangular blocks must have dimension at least k by m,
+                 where k is given by ILAENV(2,...) and m by ILAENV(5,...)
+            = 6: the crossover point for the SVD (when reducing an m by n
+                 matrix to bidiagonal form, if max(m,n)/min(m,n) exceeds
+                 this value, a QR factorization is used first to reduce
+                 the matrix to a triangular form.)
+            = 7: the number of processors
+            = 8: the crossover point for the multishift QR and QZ methods
+                 for nonsymmetric eigenvalue problems.
+            = 9: maximum size of the subproblems at the bottom of the
+                 computation tree in the divide-and-conquer algorithm
+                 (used by xGELSD and xGESDD)
+            =10: ieee NaN arithmetic can be trusted not to trap
+            =11: infinity arithmetic can be trusted not to trap
+
+    NAME    (input) CHARACTER*(*)
+            The name of the calling subroutine, in either upper case or
+            lower case.
+
+    OPTS    (input) CHARACTER*(*)
+            The character options to the subroutine NAME, concatenated
+            into a single character string.  For example, UPLO = 'U',
+            TRANS = 'T', and DIAG = 'N' for a triangular routine would
+            be specified as OPTS = 'UTN'.
+
+    N1      (input) INTEGER
+    N2      (input) INTEGER
+    N3      (input) INTEGER
+    N4      (input) INTEGER
+            Problem dimensions for the subroutine NAME; these may not all
+            be required.
+
+   (ILAENV) (output) INTEGER
+            >= 0: the value of the parameter specified by ISPEC
+            < 0:  if ILAENV = -k, the k-th argument had an illegal value.
+
+    Further Details
+    ===============
+
+    The following conventions have been used when calling ILAENV from the
+    LAPACK routines:
+    1)  OPTS is a concatenation of all of the character options to
+        subroutine NAME, in the same order that they appear in the
+        argument list for NAME, even if they are not used in determining
+        the value of the parameter specified by ISPEC.
+    2)  The problem dimensions N1, N2, N3, N4 are specified in the order
+        that they appear in the argument list for NAME.  N1 is used
+        first, N2 second, and so on, and unused problem dimensions are
+        passed a value of -1.
+    3)  The parameter value returned by ILAENV is checked for validity in
+        the calling subroutine.  For example, ILAENV is used to retrieve
+        the optimal blocksize for STRTRI as follows:
+
+        NB = ILAENV( 1, 'STRTRI', UPLO // DIAG, N, -1, -1, -1 )
+        IF( NB.LE.1 ) NB = MAX( 1, N )

+
+
+    Purpose
+    =======
+
+    SPOSV computes the solution to a real system of linear equations
+       A * X = B,
+    where A is an N-by-N symmetric positive definite matrix and X and B
+    are N-by-NRHS matrices.
+
+    The Cholesky decomposition is used to factor A as
+       A = U**T* U,  if UPLO = 'U', or
+       A = L * L**T,  if UPLO = 'L',
+    where U is an upper triangular matrix and L is a lower triangular
+    matrix.  The factored form of A is then used to solve the system of
+    equations A * X = B.

+
+    NRHS    (input) INTEGER
+            The number of right hand sides, i.e., the number of columns
+            of the matrix B.  NRHS >= 0.
+
+    A       (input/output) REAL array, dimension (LDA,N)
+            On entry, the symmetric matrix A.  If UPLO = 'U', the leading
+            N-by-N upper triangular part of A contains the upper
+            triangular part of the matrix A, and the strictly lower
+            triangular part of A is not referenced.  If UPLO = 'L', the
+            leading N-by-N lower triangular part of A contains the lower
+            triangular part of the matrix A, and the strictly upper
+            triangular part of A is not referenced.
+
+            On exit, if INFO = 0, the factor U or L from the Cholesky
+            factorization A = U**T*U or A = L*L**T.
+
+    LDA     (input) INTEGER
+            The leading dimension of the array A.  LDA >= max(1,N).
+
+    B       (input/output) REAL array, dimension (LDB,NRHS)
+            On entry, the N-by-NRHS right hand side matrix B.
+            On exit, if INFO = 0, the N-by-NRHS solution matrix X.
+
+    LDB     (input) INTEGER
+            The leading dimension of the array B.  LDB >= max(1,N).

+                  positive definite, so the factorization could not be

+
+    Arguments
+    =========
+
+    UPLO    (input) CHARACTER*1
+            = 'U':  Upper triangle of A is stored;
+            = 'L':  Lower triangle of A is stored.
+
+    N       (input) INTEGER
+            The order of the matrix A.  N >= 0.
+
+    NRHS    (input) INTEGER
+            The number of right hand sides, i.e., the number of columns
+            of the matrix B.  NRHS >= 0.
+
+    A       (input) REAL array, dimension (LDA,N)
+            The triangular factor U or L from the Cholesky factorization
