     r"""Solves systems of linear and nonlinear equations using the Newton method.
 
     Args:
-        f (Callable[[...], ...]): Vector function to find its roots.
         J (Callable[[...], ...]): Jacobian of f.
+        f (VectorFunction): Vector function to find its roots.
         vec0 (np.ndarray): Initial guess of the solution. Avoid using guesses that make J a singular matrix (:math:`|J(vec0)| = 0`).
         err (float): Stopping criteria for the algorithm. Minimum difference between the to last consecutive solutions.
