Hi rooters,
I am trying to re-use my member function, which was initially ment to
work with ROOT::Match::Functor, but I don't how to get TF2 working
with it.
Is it possilble at all to use TF2 with member functions?
Using with Functor:
ROOT::Math::Functor f(this,TreeWalk::DoLikelihoodFitPoissonMinimize,2);
Signature:
Double_t DoLikelihoodFitPoissonMinimize(const double* xval) const;
I think I have to create a wrapper function to fit the expected signature of TF2:
Double_t TreeWalk::DoLikelihoodFitPoissonMinimizeSep(double* x, double* y) {
Double_t xval[2] = {
*x,
*y
};
return DoLikelihoodFitPoissonMinimize(xval);
};
it would be nice to get some hints to get it finally working.
Best Regards,
Robert
