Suppose I have this function with multiple peaks that ranges from time = 2000 s to time = 7000 s.

Suppose there are five peaks and they are seperated evenly apart.

Suppose I want to pick the third peak.

How would I do this in MATLAB?

t=0:0.1:30
y=sin(t)
[peaks,idx]=findpeaks(y)

%the third peak is

peaks(3)

The findpeaks function is part of the Signal Processing Toolbox.
