isSkewPersymmetricMatrix

Test if a value is a skew-persymmetric matrix.

Usage

var isSkewPersymmetricMatrix = require( '@stdlib/assert/is-skew-persymmetric-matrix' );

isSkewPersymmetricMatrix( value )

Tests if a value is a skew-persymmetric matrix.

var ndarray = require( '@stdlib/ndarray/ctor' );

var arr = ndarray( 'generic', [ 2, 0, 0, -2 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var bool = isSkewPersymmetricMatrix( arr );
// returns true

Examples

var ndarray = require( '@stdlib/ndarray/ctor' );
var isSkewPersymmetricMatrix = require( '@stdlib/assert/is-skew-persymmetric-matrix' );

var arr = ndarray( 'generic', [ 1, 0, 0, -1 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var out = isSkewPersymmetricMatrix( arr );
// returns true

out = isSkewPersymmetricMatrix( [ 1, 2, 3, 4 ] );
// returns false

out = isSkewPersymmetricMatrix( {} );
// returns false

out = isSkewPersymmetricMatrix( null );
// returns false
