Example to illustrate deconvolution function (class TSpectrum).

void Deconvolution() {
Int_t i;
const Int_t nbins = 256;
Double_t xmax = nbins;
Double_t source[nbins];
Double_t response[nbins];
TString dir = gROOT->GetTutorialDir();
TString file = dir+"/spectrum/TSpectrum.root";
TFile *f = new TFile(file.Data());
TH1F *h = (TH1F*) f->Get("decon1");
TH1F *d = (TH1F*) f->Get("decon_response");
for (i = 0; i < nbins; i++) source[i]=h->GetBinContent(i + 1);
for (i = 0; i < nbins; i++) response[i]=d->GetBinContent(i + 1);
TSpectrum *s = new TSpectrum();
for (i = 0; i < nbins; i++) d->SetBinContent(i + 1,source[i]);
d->Draw("SAME L");
