- * 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.
- * The output is a vector B with indices 0..n-1 that describes a polynomial
- * that fits the data, such the sum of 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.
- *
- * 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 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 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.
