scipy.linalg.cho_solve_banded

scipy.linalg.cho_solve_banded((cb, lower), b, overwrite_b=False)

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

Parameters :

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

cb is the Cholesky factorization of A, as given by cholesky_banded. lower must be the same value that was given to cholesky_banded.

b : array

Right-hand side

overwrite_b : bool

If True, the function will overwrite the values in b.

Returns :

x : array

The solution to the system A x = b
