# ishermitian

Hermitian matrix test.

## Syntax

R = ishermitian(A)

R = ishermitian(A,tol)

## Inputs

`A`- The variable to test.
`tol`- The tolerance for the test (default 0).

## Outputs

- R
- A logical 1 when
`A`is a hermitian matrix, and 0 otherwise.

## Example

Matrix
example:

`R = ishermitian([1,2+7i,3;2-7i,4,5;3,5,6])`

`R = 1`

## Comments

A Hermitian matrix is equal to its transposed complex conjugate.

`tol` applies as follows:

norm(`A-A.'`,'inf')/norm(`A`,'inf') `tol`.
