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.
Returns: x : array
The solution to the system A x = b
