numpy.triu_indices_from(arr, k=0)[source]¶

Return the indices for the upper-triangle of arr.

See triu_indices for full details.

Parameters:	arr : ndarray, shape(N, N) The indices will be valid for square arrays. k : int, optional Diagonal offset (see `triu` for details).
Returns:	triu_indices_from : tuple, shape(2) of ndarray, shape(N) Indices for the upper-triangle of arr.
