class ROOT::Math::IParametricGradFunctionMultiDim: public ROOT::Math::IParametricFunctionMultiDim


    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.

    @ingroup  ParamFunc

This class is also known as (typedefs to this class)

ROOT::Fit::Fitter::IGradModelFunction, ROOT::Math::IParamMultiGradFunction

Function Members (Methods)

This is an abstract class, constructors will not be documented.
Look at the header to check for available constructors.

      Virtual Destructor (no operations)

{}

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

      Evaluate the all the derivatives (gradient vector) of the function with respect to the parameters at a point x.
      It is optional to be implemented by the derived classes for better efficiency

double ParameterDerivative(const double* x, const double* p, unsigned int ipar = 0) const

      Evaluate the partial derivative w.r.t a parameter ipar from values and parameters
