06 Sep 2011	Peak finding and measurement Function to locate and measure the positive peaks and valleys in noisy data sets.	Tom O'Haver	When looking at a signal for the first time, it is best to use iPeak.m, iSignal.m, or ipf.m to inspect the data interactively. All of these can be downloaded from the Matlab File Exchange or from http://terpconnect.umd.edu/~toh/spectrum/SignalProcessingTools.html Use the "pan and zoom" capabilities of these programs to inspect the whole signal closely. If the signal has important features that cover a very wide amplitude range or are superimposed on a much larger baseline or background, then those features may not be visible when the entire signal is plotted normally. Try using a semilog(x,y) plot, or use iSignal's semilog mode (H key).	Comment only
05 Sep 2011	Peak finding and measurement Function to locate and measure the positive peaks and valleys in noisy data sets.	mohammad	i have a .xls file, i saved data of that in a matrix like : r=xlsread(.xls) now its needed to find peaks but this discrete data (r) is noisy data and using of 'findpeaks' command give me a lot of numbers of peaks (because of nois). i think your code can help me. so, could you tell me how can i use this? best regard	Comment only
