null.space {MSBVAR}R Documentation

Find the null space of a matrix

Description

Computes the null space of A for an arbitrary linear system of the form Ax = b.

Usage

null.space(x)

Arguments

x m x n A matrix of a linear system Ax = b

Details

Computes the null space via singular value decomposition (SVD) of A by finding the columns of the SVD of A that correspond to the non-singular column vectors that span A.

Value

Returns an m x q matrix that is the null space, where q is the rank of A.
