class ROOT::Math::IParametricFunctionMultiDim: public ROOT::Math::IBaseFunctionMultiDim, 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.

    @ingroup  ParamFunc

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

ROOT::Math::WrappedMultiTF1::BaseParamFunc, ROOT::Fit::FitResult::IModelFunction, ROOT::Math::IParamMultiFunction, ROOT::Math::IParametricGradFunctionMultiDim::BaseParamFunc, ROOT::Fit::Fitter::IModelFunction

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) const

      Evaluate function at a point x and for given parameters p.
      This method does not change the internal status of the function (internal parameter values).
      If for some reason one prefers caching the parameter values, SetParameters(p) and then operator()(x) should be
      called.
      Use the pure virtual function DoEvalPar to implement it

return DoEvalPar(const double* x, const double* p) const

double DoEval(const double* x) const

      Implement the ROOT::Math::IBaseFunctionMultiDim interface DoEval(x) using the cached parameter values
