numeric::svd

Numerical singular value decomposition of a matrix

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

Syntax

numeric::svd(A, options)

Description

numeric::svd is equivalent to numeric::singularvectors. For details and examples, see numeric::singularvectors.

Parameters

A

A numerical matrix of domain type DOM_ARRAY, DOM_HFARRAY, or of category Cat::Matrix.

Return Values

List [U, d, V, resU, resV]. U is a unitary square float matrix whose columns are left singular vectors. The list d contains the singular values. V is a unitary square float matrix whose columns are right singular vectors. The lists of float residues resU and resV provide error estimates for the numerical data.
