Searching for non maximal values

Hi, I am looking at ground reaction force data and wanting to look at the maximum values of the 1st and 2nd peaks as well as finding out the time of each event. So far i have managed to use [max_value, max_position] = max (variable) for the peak with the highest value. However I'm not sure how to find the maximum value and timing of the lower peak.

As well as the maximum values I am also interested in finding the minimum value between the two peaks (see attachment). I have managed to get the value but again struggling to figure out how to get the time of the event.

Any help would be much appreciated

See findpeaks . If you have determined the peak positions, you can use

[minValue, minPos] = min(Signal(peak(1):peak(2)))

to find the minimal value between two peaks.
