- Learn to use plot.
- Learn how to find the local peaks on a curve. That would likely involve the findpeaks function.
- Learn how to tell plot to draw on the previous figure just created, which means to learn about the hold command in MATLAB.
Essentially, you need to start to learn some basic tools in MATLAB. If a problem is too difficult for you to solve, then break it down into small parts. Solve each part one at a time. Then put the solution together.
