Hello, > If I have a vector , por example M= rand(418,1)
Just a question of vocabulary, are you lookng for peaks with a given width, such as or for "one-pixel" wide peaks, which are sometimes refered to as "spikes"? For spikes, you can use the cade given by Samuel, just removing the "pC". If the peaks have a given width, you can locate the minima of the second derivative, best after smoothing, e.g. http://commons.wikimedia.org/wiki/File:Desommation_trois_pics_gaussiens_21pts.svg (source code here : http://commons.wikimedia.org/wiki/File:Detection_pic_savitzky_Golay.svg#Scilab_source ) Best regards -- Christophe Dang Ngoc Chan Mechanical calculation engineer This e-mail may contain confidential and/or privileged information.
