MatrixSVBkSub

MatrixSVBkSub matrixU, vectorW, matrixV, vectorB

The MatrixSVBkSub operation does back substitution for SV decomposition.

Details

Used to solve matrix equation Ax=b after you have performed an SV decomposition.

Feed this routine the M_U, W_W and M_V waves from MatrixSVD along with your right-hand-side vector b. The solution vector x is returned as M_x.

The array b can be a matrix containing a number of b vectors and the M_x will contain a corresponding set of solution vectors.

Generates an error if the dimensions of the input matrices are not appropriate.
