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.

I've tried several approaches to detecting peaks in noisy data; this one worked best, and is exceptionally fast. Very nice work!

How should I cite this code?

hi team

I am very new at this. How do I make this code find multiple peaks?

Thanks
