From: Mustapha on 4 May 2010 05:19 Hello ; i want to do a numerical integration of a signal. The latter is a raw data (not an explicit function like f(t) = t^2). The point is that I need a vector as output and not only one value . In other words, I have a signal as input , and I should have a signal as output. Do you have something to help many thanks, Best M.
