scipy.linalg.lu_solve

scipy.linalg.lu_solve((lu, piv), b, trans=0, overwrite_b=False)

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

Returns :

x : array

Solution to the system
