External module "assert/is-nonsymmetric-matrix/docs/types/index.d"

Export assignment isNonSymmetricMatrix

• isNonSymmetricMatrix(v: any): boolean

• Tests if a value is a non-symmetric matrix.

  Notes

  • The implementation must rely on manually checking that \(M_{ij} \neq M_{ji}\), and, while element access is deterministic, no way exists to prevent cache misses outside of reordering the underlying matrix elements, thus incurring a larger performance penalty than just "jumping around" in a single pass.
  • Worst case scenario: O(N^2).

  Parameters

  • v: any

    value to test

  Returns boolean

  boolean indicating if a value is a non-symmetric matrix

  Example

  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
  
  bool = isNonSymmetricMatrix( [] );
  // returns false
