Detailed Description

Single parameter function abstract base class.

This class implements the abstract interface for a one parameter function. This function is for example used for integration or numerical computation of derivatives. This class has no members. The only pure virtual method that needs to be implemented by the derived class is the eval() method that provides function evaluation at a given value x, e.g. y=eval(x).
