编辑： Wayne King 2013-10-23

Hello all,

I have some data and need a way to reliablly find the peaks of the data set. The picture below shows the plotted data. There are 19 peaks on each side of the data for a total of 38 peaks. I have tried using the findpeaks function, however it seems to pick up random spots in the data. I am consisently trying to find all 38 peaks.

Thanks

How many peaks did you find with findpeaks ?

And, I suppose while we're asking, what options did you use/have you tried to rid the spurious peaks from the results???? findpeaks does have quite a lot of flexibility in what it thinks is a qualifying peak depending on the inputs given.
