Hi,
I am struggling to implement the MnHesse function in Minuit2. Is there an example (c++) available for a call where a minimum has been found? I tried Minos but I am constantly getting the error message:
MnMinos.cxx:90: ROOT::Minuit2::MinosError ROOT::Minuit2::MnMinos::Minos(unsigned int, unsigned int, double) const: Assertion `fMinimum.IsValid()’ failed.
Thanks
