-/**
- * Solves a linear least squares problem to obtain a N degree polynomial that fits
- * the specified input data as nearly as possible.
- *
- * Returns true if a solution is found, false otherwise.
- *
- * The input consists of two vectors of data points X and Y with indices 0..m-1
- * along with a weight vector W of the same size.
- *
- * The output is a vector B with indices 0..n that describes a polynomial
- * that fits the data, such the sum of W[i] * W[i] * abs(Y[i] - (B[0] + B[1] X[i]
- * + B[2] X[i]^2 ... B[n] X[i]^n)) for all i between 0 and m-1 is minimized.
- *
- * Accordingly, the weight vector W should be initialized by the caller with the
- * reciprocal square root of the variance of the error in each input data point.
- * In other words, an ideal choice for W would be W[i] = 1 / var(Y[i]) = 1 / stddev(Y[i]).
- * The weights express the relative importance of each data point.  If the weights are
- * all 1, then the data points are considered to be of equal importance when fitting
- * the polynomial.  It is a good idea to choose weights that diminish the importance
- * of data points that may have higher than usual error margins.
- *
- * Errors among data points are assumed to be independent.  W is represented here
- * as a vector although in the literature it is typically taken to be a diagonal matrix.
- *
- * That is to say, the function that generated the input data can be approximated
- * by y(x) ~= B[0] + B[1] x + B[2] x^2 + ... + B[n] x^n.
- *
- * The coefficient of determination (R^2) is also returned to describe the goodness
- * of fit of the model for the given data.  It is a value between 0 and 1, where 1
- * indicates perfect correspondence.
- *
- * This function first expands the X vector to a m by n matrix A such that
- * A[i][0] = 1, A[i][1] = X[i], A[i][2] = X[i]^2, ..., A[i][n] = X[i]^n, then
- * multiplies it by w[i]./
- *
- * Then it calculates the QR decomposition of A yielding an m by m orthonormal matrix Q
- * and an m by n upper triangular matrix R.  Because R is upper triangular (lower
- * part is all zeroes), we can simplify the decomposition into an m by n matrix
- * Q1 and a n by n matrix R1 such that A = Q1 R1.
- *
- * Finally we solve the system of linear equations given by R1 B = (Qtranspose W Y)
- * to find B.
- *
- * For efficiency, we lay out A and Q column-wise in memory because we frequently
- * operate on the column vectors.  Conversely, we lay out R row-wise.

- * The ATRACE_TAG macro can be defined before including this header to trace
- * using one of the tags defined below.  It must be defined to one of the
- * following ATRACE_TAG_* macros.  The trace tag is used to filter tracing in
- * userland to avoid some of the runtime cost of tracing when it is not desired.
- *
- * Defining ATRACE_TAG to be ATRACE_TAG_ALWAYS will result in the tracing always
- * being enabled - this should ONLY be done for debug code, as userland tracing
- * has a performance cost even when the trace is not being recorded.  Defining
- * ATRACE_TAG to be ATRACE_TAG_NEVER or leaving ATRACE_TAG undefined will result
- * in the tracing always being disabled.
- *
- * ATRACE_TAG_HAL should be bitwise ORed with the relevant tags for tracing
- * within a hardware module.  For example a camera hardware module would set:
- * #define ATRACE_TAG  (ATRACE_TAG_CAMERA | ATRACE_TAG_HAL)
- *
- * Keep these in sync with frameworks/base/core/java/android/os/Trace.java.
