Dear All,
Is there any trick to take a "user defined function" to a member of a class?
I've tried the follow and it didn't work.
The error message:
"Symbol A is not defined in current scope".
class probe{
public:
probe::probe();
probe::~probe();
Double_t Voigt(Double_t* x, Double_t* par);
};
Double_t probe::Voigt(Double_t* x, Double_t* par){
Double_t arg = 0;
if(par[2])
arg = (x[0] - par[1]) / par[2];
Double_t Gaus = TMath::Exp( -0.5 * arg * arg );
Double_t Lorentz = 1 / ( 1 + arg * arg );
return par[0] * ( par[3] * Gaus + ( 1- par[3] ) * Lorentz );
}
main(){
probe A;
TF1* f1 = new TF1("f1", A.Voigt, 100, 200, 4);
}
