Exercise 3 Simspons 1/3 Rule

You are required to write a Matlab function that calculates the area under the curve f(x) = 1-x-0.125x^3 + 0.25x^4 within the interval [-1.5, 3] using Simpsons 1/3 rule. You function accepts the number of segments n that you want to use for your approximation.

Try your code with n = 10, and n = 20. Compare the result with both MATLABs built-in functions
