I am new to matlab and having difficulty. I want to find indexes for maximum and minimum and put them into sets of array. Here is what I have tried. I have no clue on how to produce data for minimum X and Y indexes. Much appreciated for help!
Ry = HeelArray(:,3);
Ry2= HeelArray(:,6);
plot (Ry)
hold on
plot (Ry2)
findpeaks(Ry2, 'Minpeakheight',500);
[Minima, MinIdx] = findpeaks(Ry2, 'Minpeakheight',500);

Can you attach HeelArray in a .mat file with the paper clip icon, and attach a PNG screenshot with the green and brown frame icon.
