class ROOT::Minuit2::GenericFunction


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.

Function documentation

virtual ~GenericFunction()

{}

double operator()(const vector<double>& x) const

      Evaluates the function using the vector containing the input values.

      @param x vector of the coordinates (for example the x coordinate for a
      one-dimensional Gaussian)

      @return the result of the evaluation of the function.
