solve_triangular
(a, b, trans=0, lower=False, unit_diagonal=False, overwrite_b=False, check_finite=False)¶ Solve the equation a x = b for x, assuming a is a triangular matrix.
Parameters: - a (cupy.ndarray) – The matrix with dimension
(M, M)
. - b (cupy.ndarray) – The matrix with dimension
(M,)
or(M, N)
. - lower (bool) – Use only data contained in the lower triangle of a. Default is to use upper triangle.
- trans ({0, 1, 2, 'N', 'T', 'C'}) – Type of system to solve: ======== ========= trans system ======== ========= 0 or ‘N’ a x = b 1 or ‘T’ a^T x = b 2 or ‘C’ a^H x = b ======== =========
- unit_diagonal (bool) – If True, diagonal elements of a are assumed to be 1 and will not be referenced.
- overwrite_b (bool) – Allow overwriting data in b (may enhance performance)
- check_finite (bool) – Whether to check that the input matrices contain only finite numbers. Disabling may give a performance gain, but may result in problems (crashes, non-termination) if the inputs do contain infinities or NaNs.
Returns: The matrix with dimension
(M,)
or(M, N)
.Return type: See also
- a (cupy.ndarray) – The matrix with dimension
