# null

Null space of matrix

## Description

## Examples

## Input Arguments

## Output Arguments

## Algorithms

`null(A)`

calculates the singular value decomposition of the matrix,
`A = U*S*V'`

. The columns of `V`

that do not correspond to
nonzero singular values form a set of orthonormal basis vectors for the null space.

The "rational" basis for the null space `null(A,'r')`

is obtained from
the reduced row echelon form of `A`

, as calculated by
`rref`

.
