class ROOT::Math::IParametricGradFunctionOneDim: public ROOT::Math::IParametricFunctionOneDim, public ROOT::Math::IGradientFunctionOneDim


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.

void ParameterGradient(const double * x , double * grad )

Evaluate the derivatives of the function with respect to the parameters at a point x.
It is optional to be implemented by the derived classes

void ParameterGradient(double x , double * grad )
