cupyx.scipy.sparse.tril(A, k=0, format=None)[source]#

Return the lower triangular portion of a sparse object.

Parameters:

  • A (cupy.ndarray or cupyx.scipy.sparse) – Input array/matrix.

  • k (integer) – The top-most diagonal of the lower triangle.

  • format (string) – Sparse format of the result, e.g. 'csr', 'csc'.

Returns:

Lower triangular portion of A. Returns a sparse array when A is a sparse array, else a sparse matrix.

Return type:

cupyx.scipy.sparse
