05 Aug 2014 PeakFinder Quickly finds local maxima (peaks) or minima (valleys) in a noisy signal. Author: Nathanael Yoder Nathanael Yoder

@Frank I believe the function works as intended with the current indexing methodology. By using the same index (ii) for traversing both the valleys and the peaks, the function has to come down at least sel between each peak and two peaks can't be right next to each other. That said, please email me if you have an example of where you feel it does not work and I'd be happy to take a look.

@Jakob Are you sure you are calling this function? Line 98 in this peakfinder is: dx0 = diff(x0); % Find derivative.

Also the function unfortunately does not accept cell inputs

Thanks for catching that Tim. You were exactly right, the redundancy is an artifact from when I preallocated the matrix for speed. However, I essentially replaced this statement with the leftMin variable which is why you got the same results. The end effect is that the second part of that conditional can simply be eliminated.

Thanks again for your help and an updated version with the addition of a user defined threshold should be available shortly.

I was incorrect but there does seem to be a scale factor on the density functions

Great code but I believe line 83 should be:
density=idct1d(a_t)/N;
instead of:
density=idct1d(a_t)/R;
in order to get an accurately scaled density function.
