Fit Get / Set Parameters

Simple question : ROOT::Math::Minimizer has a SetVariableLimit function which does the same as SetParameter did in old ROOT5 TFitterMinuit . Is there an equivalent in ROOT::Math::Minimizer to GetParameter ? I don’t see anything obvious in the documentation.


The function to retrieve the parameter (i.e. the variables in the Minimizer) is :
const double * X() const see

But you might need to run Minimize before


Thanks. X() gives me just the parameter value after the fit, not the rest of the parameters that GetParameter gives me. However, since posting the question I found that GetVariableSettings( unsigned int ivar, ROOT::Fit::ParameterSettings& ) gets me all of them.
