# mldivide, \

Solve systems of linear equations *Ax = B* for
*x* when *A* is a Galois array

## Syntax

## Description

## Examples

## Input Arguments

## Output Arguments

## Limitations

The matrix `A`

must be one of these types:

A nonsingular square matrix

A matrix with more rows than columns such that

`A'*A`

is nonsingularA matrix with more columns than rows such that

`A*A'`

is nonsingular

## Algorithms

If `A`

is an *M*-by-*N* matrix
where *M* > *N*, `A\B`

is the same as
`(A'*A)\(A'*B)`

.

If `A`

is an *M*-by-*N* matrix
where *M* < *N*, `A\B`

is the same as
`A'*((A*A')\B)`

. This solution is not unique.
