ROOT::Math::IBaseParam Class Reference

Documentation for the abstract class IBaseParam.

It defines the interface for dealing with the function parameters This is used only for internal convinience, to avoid redefining the Parameter API for the one and the multi-dim functions. Concrete class should derive from ROOT::Math::IParamFunction and not from this class.
