Tomasz, If you are really desperated, there is a simple and clean solution. Replace TF1 *t[]={new TF1("g","gaus",-6,6), new TF1("p","pol1", 0,6)}; by TF1 *t[2]; t[0] = new TF1("g","gaus",-6,6); t[1] = new TF1("p","pol1", 0,6); Rene Brun Tomasz Bold wrote: > > Hi ROOTers, > I desperatelly need to perform plenty of fits of simuilar > functions.
