Message Flag in TVirtualFitter

ROOT
#1

Dear Rooters,

TMinuit provides flags to inform about the minimization status :

ā€”> erflg
But this does not (?) exist in TVirtualFitter ā€¦ :cry:
the same for :

mnstat(Double_t& fmin, Double_t& fedm, Double_t& errdef, Int_t& npari, Int_t& nparx, Int_t& istat)

Is there such possibilities to get that information ?

Many thanks !!
Cheers

Hello,

the error flag is normally returned from the TVirtualFitter method.
For example when executing a command the error flag is the return argument of the TVirtualFitter::ExecuteCommand method.
In the case of mnstat the error flag is returned from the TVirtualFitter::GetStats.

Best Regards

Lorenzo
