(20 points) Write a Matlab script that uses a sub- function that computes and plots the numerical second derivative of a passed function for an input range using an input step size, h, and the centered difference ap- proximation, i.e. the subfunction has to be a Matlab function function. Test it with the function: Q(2) = e-9 sin (27(2 - zo), where q = 1 and zo = 2, with z in the interval z (0,4]. a
