Create a function as below:

function [I] = compss(f, a, b, n) that takes a function f an interval [a,b], and an even number n and returns I, an approximation to using Composite Simpson's rule.

If the input is odd, use the error function, that already built in MATLAB, to report an error.

THe function f should be evaluated a total of n+1 times.

We are trying to apply Composite Simpson rule, and build a function with it.

Please help me write this in MATLAB. Explanation also helpful. I am new to this programming. Thanks so much!
