dpnp.tril_indices

dpnp.tril_indices(n, k=0, m=None)

Return the indices for the lower-triangle of an (n, m) array.

Parameters:

• n (int) -- The row dimension of the arrays for which the returned indices will be valid.

• k (int, optional) -- Diagonal offset (see tril for details).

• m (int, optional) -- The column dimension of the arrays for which the returned arrays will be valid. By default m is taken equal to n.

Returns:

inds -- The indices for the triangle. The returned tuple contains two arrays, each with the indices along one dimension of the array.

Return type:

tuple of arrays
