lu_solve
(lu_and_piv, b, trans=0, overwrite_b=False, check_finite=True)¶ Solve an equation system,
a * x = b
, given the LU factorization ofa
Parameters: - lu_and_piv (tuple) – LU factorization of matrix
a
((M, N)
) together with pivot indices. - b (cupy.ndarray) – The matrix with dimension
(M,)
or(M, N)
. - trans ({0, 1, 2}) –
Type of system to solve:
trans system 0 a x = b 1 a^T x = b 2 a^H x = b - 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
