MATLAB: How do i find the matching data for locs when using findpeaks()

Question

Hi

I am using the function

[pks,locs]=findpeaks()

and the locs returns the position of that pks in the data when plotting

but what I want is plotting the pks and the other coloum in the data not the locs as the x-axis

thanks in advance

Answer 1

If your peaks plot is produced by

plot(time, data)

and you're locating the peaks with

[pks,locs]=findpeaks(data);

Then, to plot the peaks as a function of time,

plot(time(locs), pks, '*')
