is anyone can help me to find a peak value for my data. i just want to detect the two highest peak from the graph for specific range of value in x-axis.. in order to make decision i need to classified the graph. i have used findpeak command as shown below, but there are a lot of peak that this function detect from my graph.
% To plot Graph
numFrames = AllData(1,:);
Width = AllData(2,:);
Height = AllData(3,:);
plot(numFrames,Height), title ('Height-Ab');
hold on
% Find peak
[pks,locs]=findpeaks(Height,'minpeakheight',160);
plot(locs,pks,'o','MarkerSize',3,'MarkerFaceColor',[1 0 0])
but i don't know how to make the command just valid for value nFrames in between 10 to 40 let say..

indesiredrange = locs > 10 & locs < 40;
pks_subset = pks(indesiredrange);
locs_subset = locs(indesiredrange);
