How to get a specified number of local maxima?

5 Ansichten (letzte 30 Tage)
I have a signal and I only want the top two or three local maxima, I don't want the 5000 maxima that the findpeaks() function gives me. Is there a way to get this? Thanks.

Have you tried specifying NPeaks? Check the documentation

You can use this function. I used this for taking top 2 frequency spectra maxima. You can find the min with the same logic.
**Update:Replace max(j) with val(j) in the function
