# isSkewCentrosymmetricMatrix
> Test if a value is a [skew-centrosymmetric matrix][centrosymmetric-matrix].
## Usage
```javascript
var isSkewCentrosymmetricMatrix = require( '@stdlib/assert/is-skew-centrosymmetric-matrix' );
```
#### isSkewCentrosymmetricMatrix( value )
Tests if a value is a [skew-centrosymmetric matrix][centrosymmetric-matrix].
```javascript
var ndarray = require( '@stdlib/ndarray/ctor' );
var buffer = [
1, 2, 3,
4, 0, -4,
-3, -2, -1
];
var arr = ndarray( 'generic', buffer, [ 3, 3 ], [ 3, 1 ], 0, 'row-major' );
var bool = isSkewCentrosymmetricMatrix( arr );
// returns true
```
## Examples
```javascript
var ndarray = require( '@stdlib/ndarray/ctor' );
var isSkewCentrosymmetricMatrix = require( '@stdlib/assert/is-skew-centrosymmetric-matrix' );
var arr = ndarray( 'generic', [ 2, 1, -1, -2 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var out = isSkewCentrosymmetricMatrix( arr );
// returns true
out = isSkewCentrosymmetricMatrix( [ 1, 2, 3, 4 ] );
// returns false
out = isSkewCentrosymmetricMatrix( {} );
// returns false
out = isSkewCentrosymmetricMatrix( null );
// returns false
```
