Class from which all the other classes, representing functions, inherit.

That is why it defines only one method, the operator(), which allows to call the function.

virtual double ROOT::Minuit2::GenericFunction::operator() ( const std::vector< double > &  x) const
pure virtual

Evaluates the function using the vector containing the input values.

xvector of the coordinates (for example the x coordinate for a one-dimensional Gaussian)
the result of the evaluation of the function.
