Matlab: Numerical differentiation Make a function (Matlab) that takes as input two numbers a and h and any function f(x). Calculate using the three elements: backward difference first order derivative; forward difference first order derivative; first order derivative central difference; second order derivative central difference. And return the f(a) and f'(a) values. 1 Function (int)= difN (a,h, f) 2 L%to be continue
