d = rand(100,1); % assumed data
[vals,loc] = maxk(d,2); % first two peaks(mnaximum values) sample values and locations
plot(d); hold on; % plot original samples
plot(loc,vals,'rv', 'MarkerFaceColor', 'r'); % plot peak values

Yeah, I got you. Use findpeaks to get all peak values of the samples
d = rand(100,1); % assumed data
[vals,locs] = findpeaks(d);
[val,loc] = maxk(vals,2); % first two peaks(mnaximum values) sample values and locations
plot(d); hold on; % plot original samples
plot(locs(loc),val,'rv', 'MarkerFaceColor', 'r'); % plot peak values
