Hi Guys,
        Very simple macro:

#include <TMath.h>

double eff(double tau){
  return 0.0140213*(
		    TMath::Atan((30.5012/tau-7.3399)/2.0)-
		    TMath::Atan((3.25151/tau-4.62383)/2.0)
		    );
}

double test(){

  cout<<eff(0.1)<<endl;
  cout<<eff(1.0)<<endl;

  return 0.0;
}




When I try doing:

.L que.C
test()




where que.C is the name of the file.....it complains that it can't find
TMath

?

cheers

Mat
