I have the peak values for the following graph ..but i need the number of peak values in the plot.
load engine_run.dat
engine_state = engine_run(:,1);
time = engine_run(:,2);
findpeaks(time,engine_state)
xlabel('time')
ylabel('engine state')

Use findpeaks with outputs:
[pks,locs] = findpeaks(time,engine_state);
The number of peaks will be:
numPeaks = numel(pks)
The ‘locs’ output will be the times they occurred.

I would use the diff function on the locs output and then see if any of those values are less than five seconds.
If they are, then using that result catgorize them as either 0 or 1, depending on whatever criteria you are using.
