Using MATLAB: Create a script (int.m) that accepts a function f(x) and stepsize h then calculates the integral using the Midpoint rule, Trapezoid rule and Simpsons rule. Run this script for h = 1, 0.1, 0.01, 0.001 and write this data to a file (int.txt).

The data file should have the following header values:

*Here is the midpoint, trapezoid, and simpson's rule

Please solve using only MATLAB. Thanks!
