scipy.linalg.lu_solve(lu_and_piv, b, trans=0, overwrite_b=False, check_finite=True)[source]

Solve an equation system, a x = b, given the LU factorization of a

Parameters :

(lu, piv) :

Factorization of the coefficient matrix a, as given by lu_factor

b : array

Right-hand side

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

check_finite : boolean, optional

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 :

x : array

Solution to the system
