ROOT::Math::IBaseFunctionOneDim Class Referenceabstract

Interface (abstract class) for generic functions objects of one-dimension Provides a method to evaluate the function given a value (simple double) by implementing operator() (const double ).

In addition it defines the interface for copying functions via the pure virtual method Clone(). Derived classes must implement the pure virtual private method DoEval(double ) for the function evaluation in addition to Clone(). An interface for evaluating the function passing a vector (like for multidim functions) is also provided
