Hello,

I am new to matlab. I got signals from the sensors for force with respect to time. The values of time and force are stored in respetive columns after importing it in matlab through excel file. Thus, I need to find the average values within particular range of values in graph (highlighted in red colour). Can someone help?

Thanks

Preshit

Use the negative of your signal (essentially flipping it upside-down) so the sharp dips are now peaks. Then use either findpeaks or islocalmax to isolate the indices of the peaks. Use those indices to calculate the mean between them. (If I had your signal, I could write code specific to your problem. With only a picture, I can only describe the approach.)
