16 Dec 2008	Kernel Density Estimator Reliable and extremely fast kernel density estimator for one-dimensional data Author: Zdravko Botev	I was incorrect but there does seem to be a scale factor on the density functions
16 Dec 2008	Kernel Density Estimator Reliable and extremely fast kernel density estimator for one-dimensional data Author: Zdravko Botev	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.
16 Dec 2008	kernel density estimation fast and accurate state-of-the-art bivariate kernel density estimator Author: Zdravko Botev

30 Nov 2009	PeakFinder Quickly finds local maxima (peaks) or minima (valleys) in a noisy signal. Author: Nate Yoder	Andres	I was happily using peakfinder until I had severe trouble with a dataset beginning with repeated values. I've boiled it down to a short example: t = [49 49 54 49 -57 46 -96 -10 39 0]; startI1 = 1; [Loc1, Peak1] = peakfinder(t(startI1:end),20); startI2 = 2; [Loc2, Peak2] = peakfinder(t(startI2:end),20); figure plot(t,'b.-') hold on plot(Loc1-1+startI1,Peak1,'ro') plot(Loc2-1+startI2,Peak2,'go') Problems: 1) The first call returns a wrong result (Loc1 = 2, Peak1 = 49). 2) The second call returns all three peaks, but the last one appears twice (Loc2 = [2 5 8 8].', Peak2 = [54 46 39 39].'). I hope these issues can be fixed as peakfinder works promisingly fast. A minor suggestion: if the input is a row vector the output should be a row vector, too. Regards Andres
