Numerical Integration Using Trapezoidal Rule in MATLAB 

In this video, we will see how to numerically integrate any data using MATLAB. We have used the command trapz in MATLAB which uses trapizoidal rule to calculate area under any curve. We have also used cumtrapz to calculate cumulative integral over a range.
**In the analytical example, I have mistakenly flipped the terms so it looks like -2, but the answer to the integral should be +2.
