RooAbsFunc Class Referenceabstract
Roofit » Roofitcore

Abstract interface for evaluating a real-valued function of one real variable and performing numerical algorithms on it.

The purpose of this interface is to decouple RooAbsArg-specific implementations from numerical algorithms that only need a simple function evaluation interface. The domain of the function is assumed to be an n-dimensional box with edge coordinates specified by the the getMinLimit() and getMaxLimit() methods.
