Package  Description 

org.apache.commons.math3.analysis.function 
The
function package contains function objects that wrap the
methods contained in Math , as well as common
mathematical functions such as the gaussian and sinc functions. 
org.apache.commons.math3.analysis.polynomials 
Univariate real polynomials implementations, seen as differentiable
univariate real functions.

org.apache.commons.math3.fitting 
Classes to perform curve fitting.

org.apache.commons.math3.optimization.fitting
