isSkewCentrosymmetricMatrix

Test if a value is a skew-centrosymmetric matrix.

Usage

var isSkewCentrosymmetricMatrix = require( '@stdlib/assert/is-skew-centrosymmetric-matrix' );

isSkewCentrosymmetricMatrix( value )

Tests if a value is a skew-centrosymmetric matrix.

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

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
