class ROOT::Math::IParametricFunctionOneDim: public ROOT::Math::IBaseFunctionOneDim, public ROOT::Math::IBaseParam


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.

Function Members (Methods)

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

Function documentation

double operator()(const double * x, const double * p )

Evaluate function at a point x and for parameters p.
This method may be overloaded for better efficiencies by the users
For example the method could not change the internal parameters value kept in the derived class.
This behaviour is not defined and is left intentionally to the implementation of the derived classes

return operator()(x)
