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