scipy.linalg.cho_solve(c_and_lower, b, overwrite_b=False, check_finite=True)[source]

Solve the linear equations A x = b, given the Cholesky factorization of A.

Parameters :

(c, lower) : tuple, (array, bool)

Cholesky factorization of a, as given by cho_factor

b : array

Right-hand side

check_finite : boolean, optional

Whether to check the input matrixes contain only finite numbers. Disabling may give a performance gain, but may result to problems (crashes, non-termination) if the inputs do contain infinities or NaNs.

Returns :

x : array

The solution to the system A x = b
