Problem 1366. Finding peaks

Created by Selvaraaju Murugesan

Solve Later

Find the peak values in the signal. The peak value is defined as the local maxima. For example, x= [1 12 3 2 7 0 3 1 19 7]; peaks = [12 7 3 19];

Hint: Plot x to visually analyse the signal and get the idea of finding the peak. Another hint : first derivative
