I have the following graph in which I used function findpeaks and MinPeakHeight to find the peaks that I'm interested in.
[pks,locs]=findpeaks(filter_sgo,'MinPeakHeight',limiar,'MinPeakDistance',minpkdist);
Now I want to find the local minimums but only before the peaks that I have already detected (red points of the picture). I know I have to invert the signal and use findpeaks again, but I can't figure out how to only detect before a peak.
Thanks a lot.
