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
virtual double | DoParameterDerivative(const double* x, const double* p, unsigned int ipar) 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
Evaluate the partial derivative w.r.t a parameter ipar from values and parameters
Evaluate all derivatives using cached parameter values
Evaluate partial derivative using cached parameter values
