value to test
boolean indicating if a value is a persymmetric matrix
var ndarray = require( `@stdlib/ndarray/ctor` );
var arr = ndarray( 'generic', [ 1, 2, 3, 1 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var bool = isPersymmetricMatrix( arr );
// returns true
bool = isPersymmetricMatrix( [] );
// returns false
Tests if a value is a persymmetric matrix.
