kron
(a, b)[source]¶ Kronecker product of 2 sparse arrays.
Parameters: b (a,) – The arrays over which to compute the Kronecker product. Returns: res – The kronecker product Return type: COO Raises: ValueError
– If all arguments are dense or arguments have nonzero fill-values.Examples
>>> a = eye(3, dtype='i8') >>> b = np.array([1, 2, 3], dtype='i8') >>> res = kron(a, b) >>> res.todense() # doctest: +SKIP array([[1, 2, 3, 0, 0, 0, 0, 0, 0], [0, 0, 0, 1, 2, 3, 0, 0, 0], [0, 0, 0, 0, 0, 0, 1, 2, 3]], dtype=int64)
