You will start by learning MATLAB. Sorry, but it seems you have made no effort at all, so it seems clear you have been told to do this, and you just gave up.
So spend a couple of hours and do some reading. The MATLAB Onramp tutorials are fine for that. But you can just as easily find youtube videos that teach you to write MATLAB code.
The integrals are almost certainly doable using simple sums, thus effectively rectangle rule. At most, you would use trapezoidal rule. For that you would call trapz. But typically these computations are just done using a sum.
