Finite difference methods, for applications including gradient computation and gradient checks.

Important notes

The output of your function of interest should be a NumPy array. If your function is scalar-valued, change it to a NumPy array with:

import numpy as np

def function(input_value: float) -> np.ndarray:
    scalar_output_value = old_function(input_value)
    return np.array([scalar_output_value])
