AlgError | AlgMatrixSVSolve (AlgMatrix aMat, double *bVec, double tol, int *dstIC) |
Solves the matrix equation A.x = b for x, where A is a matrix with at least as many rows as columns. On return the matrix A is overwritten by the matrix U in the singular value decomposition: A = U.W.V'. | |
AlgError | AlgMatrixSVDecomp (AlgMatrix aMat, double *wVec, AlgMatrix vMat) |
Performs singular value decomposition of the given matrix (A) and computes two additional matricies (U and V) such that: A = U.W.V' where V' is the transpose of V. The code for AlgMatrixSVDecomp was derived from: Numerical Recipies function svdcmp(), EISPACK subroutine SVD(), CERN subroutine SVD() and ACM algorithm 358. See AlgMatrixSVSolve() for a usage example. | |
AlgError | AlgMatrixSVBackSub (AlgMatrix uMat, double *wVec, AlgMatrix vMat, double *bVec) |
Solves the set of of linear equations A.x = b where A is input as its singular value decomposition in the three matricies U, W and V, as returned by AlgMatrixSVDecomp(). The code for AlgMatrixSVBackSub was derived from: Numerical Recipies function svbksb(). |
