class ROOT::Math::IBaseFunctionMultiDim


       Documentation for the abstract class IBaseFunctionMultiDim.
       Interface (abstract class) for generic functions objects of multi-dimension
       Provides a method to evaluate the function given a vector of coordinate values,
       by implementing operator() (const double *).
       In addition it defines the interface for copying functions via the pure virtual method Clone()
       and the interface for getting the function dimension via the NDim() method.
       Derived classes must implement the pure private virtual method DoEval(const double *) for the
       function evaluation in addition to NDim() and Clone().

virtual ~IBaseFunctionMultiDim()
         virtual destructor

{}
IBaseFunctionMultiDim * Clone() const
          Clone a function.
          Each derived class must implement his version of the Clone method

unsigned int NDim() const
         Retrieve the dimension of the function

double operator()(const double* x) const
          Evaluate the function at a point x[].
          Use the pure virtual private method DoEval which must be implemented by the sub-classes

return DoEval(x)
