Hello,
Would you please assist me to find minimums and maximums of repetitive numbers in the attached matrix (EXCEL file). Actually, corresponding values of red ovals and green and blue arrows are different events recorded as biomechanical data during human gait. I am a beginner and need explanation to understand how to calculate the corresponding values. Thank you very much.

Might need to filter slightly to smooth data to obtain consistent results.
redA=islocalmax(a)&a>.1;
greenA=islocalmin(diff([a(1);a]))&a<.03;
blueA=islocalmin(a)&a<.03

Your filter could be as simple as:
a=movmean(a,4);
