How can I copy the value of points around the result of a specific function?

How can I copy the value of points around the result of a specific function? E.g. Let us suppose I am using findpeaks to find the peaks of a given set of data, but I also want the code to copy the value of the point following the peak (the next one). Is there a way to do so?

I don't know if I understand the question correctly, but did you mean something like this (using findpeaks() as example)

data = rand([1 10]);
plot(data)
[pks,locs] = findpeaks(rand([1 10]));

disp('Current locations / values:');[locs;pks]

%Current locations / values:
%ans =
%
%    4.0000    7.0000
%    0.3520    0.7838

disp('Next locations / values (+1)');[(locs+1);data(locs+1)]

%Next locations / values (+1)
%ans =
%
%   5.0000    8.0000
%   0.1528    0.0175

That's exactly what I wanted. The problem is, I wasn't keeping track of the location of the points. I was using something like: X = findpeaks(rand([1 10])); Which gives me just the values.

Problem solved! Thanks a lot!
