# scipy.linalg.cho_solve_banded¶

scipy.linalg.cho_solve_banded(cb_and_lower, b, overwrite_b=False, check_finite=True)[source]

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, optional If True, the function will overwrite the values in b. check_finite : bool, 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. x : array The solution to the system A x = b
