# 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
