Write a MATLAB code to create the Natural Cubic Spline. The code will use the MATLAB built in backslash operator to solve the system Ax = b. Another useful command is: zeros(n). Modify your code to find the Clamped Cubic Spline Use your code to form both the natural and the clamped spline to approximate f(x) sin(x) on the interval [0, 7 using the two interior points and 2
