Detailed Description

SVD - Singular Value Decomposition Rrepresentation of some input matrix.

The SVD Decomposition of a matrix, A, can be written as U*S*V^T where S is a diagonal matrix of singular values, U and V are orthogonal matrices. This decompition allows for fast solving a a system of linear equations. Here, the Lapack Fortran code for DGESVD is called. See lapack.h for more information
