## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var isSymmetricMatrix = require( '@stdlib/assert/is-symmetric-matrix' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### isSymmetricMatrix( value )
|
||
|
|
|
||
|
|
Tests if a value is a [symmetric matrix][symmetric-matrix].
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var ndarray = require( '@stdlib/ndarray/ctor' );
|
||
|
|
|
||
|
|
var arr = ndarray( 'generic', [ 0, 1, 1, 2 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
|
||
|
|
var bool = isSymmetricMatrix( arr );
|
||
|
|
// returns true
|
||
|
