ROOT::Minuit2::MnFcn Class Reference

Wrapper class to FCNBase interface used internally by Minuit.

Apply conversion from calling the function from a Minuit Vector (MnAlgebraicVector) to a std::vector for the function coordinates. The class counts also the number of function calls. By default counter start from zero, but a different value might be given if the class is instantiated later on, for example for a set of different minimizaitons Normally the derived class MnUserFCN should be instantiated with performs in addition the transformatiopn internal-> external parameters
