WebIn linear algebra, the singular value decomposition (SVD) is a factorization of a real or complex matrix.It generalizes the eigendecomposition of a square normal matrix with an orthonormal eigenbasis to any matrix. It is related to the polar decomposition.. Specifically, the singular value decomposition of an complex matrix M is a factorization of the form = , … WebThe software package Regularization Tools, Version 4.1 (for MATLAB Version 7.3), consists of a collection of documented MATLAB functions for analysis and solution of discrete ill-posed problems.
