Dan,
see the simple example below
compile and link it with
g++ -o dan dan.cxx `root-config --cflags --libs`
//file dan.cxx
#include "TFile.h" #include "TTree.h" #include "TRandom3.h"
int main()
{
TFile hfile("dan.root","RECREATE");
double px,py;
TTree *T = new TTree("T","Demo");
T->Branch("px",&px,"px/D");
T->Branch("py",&py,"py/D");
TRandom3 r(0);
for ( int i=0; i<10000; i++) {
r.Rannor(px,py); //px and py will be two gaussian random numbers T->Fill();
T->Print();
T->Write();
return 0;
}
