Write a MATLAB user-defined function that determines the first derivative of a f

Question

Write a MATLAB user-defined function that determines the first derivative of a function that is given by a set of discrete points with equal spacing. For the function name use yd = First- Deriv (x, y). The input arguments and y are vectors with the coordinates of the points, and the output argument yd is a vector with the values of the derivative at each point. At the first and last points, the function should calculate the derivative with the three-point forward and backward difference formulas, respectively. At all the other points FirstDeriv should use the two-point central difference formula. Use FirstDeriv to calculate the derivative of the function that is given in Problem 6.1.
