how do i find the matching data for locs when using findpeaks()

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

What do you mean by plotting the pks and the other coloum in the data?

[chengwei zhang]

in the CeramicRe.txt, there are two coloums of data, the one on the right side is the pks and the left side is time, but the code i used only return the pks with its position number in the data but i want to plot the pks vs. time

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, '*')
