Hi,

this is like to google drive folder with a data and codes:

This is a development of my code. I have previously written in support about function folding, and you contributed:

Function convolution with parameters

Hello! I have a problem with function convolution. I used Breit-Wigner function for fitting TH1: TF1 *core3 = new TF1("core3","[0]*TMath::BreitWigner(x,[1],[2])", inf, sup); But now i need describe TH1 with convolution by BW and Gausn. I tried: TF1Convolution *core3_conv = new TF1Convolution("[0]*TMath::BreitWigner(x,[1],[2])", "gausn(3)", inf, sup); TF1 *core3 = new TF1("core3", *core3_conv, inf, sup, core3_conv->GetNpar()); and TF1 *core3 = new TF1("core3", "NSUM(*[0]*TMath::BreitWigner(…
