Detailed Description

Univariate functions as Java objects.

This package contains a few utilities classes representing univariate mathematical functions. They are useful, for example, when one wants to pass an arbitrary function of one variable as argument to a method. They allow one to apply mathematical operations like squaring, power, etc. on generic functions. There are also utilities for numerical differentiation and integration.
