Please I need the Matlab code. This is an assignment for Matlab Grader

Cubic Splines O solutions submitted (max: 5) Write a script to calculate the cubic spline interpolation for a set of data points datx and daty, given below. The referenced code, cubic_spline_coefs.m takes as input your set of datapoints, datx and daty, and calculates and returns the ai, bi, C;, and d; coefficients necessary for cubic spline interpolation. Interpolate over the points from 0 to 4 in increments of 0.01 (call this variable x). Make sure to calculate the cubic spline interpolation (call this variable spline). The data points are given by (0,1), (0.5, 0.5), (2, e?), and (4, e4). See the template to help you get started. You can test your code by plotting the data points and the cubic spline interpolatnt on the same graph. Does the interpolating function go through the data points? 3. (20 pts) Write a MATLAB script to calculate the natrual cubic spline interpolation for a set of data points datx and daty, given below. The referenced code on Matlab Grader, cubic_spline_coefs.m, takes as input your set of datapoints, datx and daty, and calculates and returns the di, bi, Ci, and di coefficients necessary for cubic spline interpolation. Interpolate over the points from 0 to 4 in increments of 0.01 (call this variable x). Make sure to calculate the cubic spline interpolation (call this variable spline). The data points are given by (0,1), (0.5, 0.5), (2, e?), and (4, e4). See the template to help you get started
