MATLAB: Finding x axis in findpeaks

Question

Hello

Please I am able to find the peak of my plot

using

pks = findpeaks(m);

This only shows me the values on the y axis

I want to find the corresponding values in the x axis too. Also I will like results of the x axis to come out in the multiple of 2 ( x * 2)

I will be grateful for any help

thanks

Tine

Answer 1

doc findpeaks

clearly shows there are numerous ways to call the function, including:

[pks,locs] = findpeaks(data)

where locs is the index locations of the peaks given in pks.

Reading the documentation should always be your first stop when you want to know how to do something, especially with a function you have already identified so that it is simple to go to the help page of!
