| Package | Description | 
|---|---|
| org.apache.commons.math3.analysis.integration | Numerical integration (quadrature) algorithms for univariate real functions. | 
| org.apache.commons.math3.fitting.leastsquares | This package provides algorithms that minimize the residuals
 between observations and model values. | 
| org.apache.commons.math3.ode | 
 This package provides classes to solve Ordinary Differential Equations problems. | 
| org.apache.commons.math3.optim | 
  Generally, optimizers are algorithms that will either
   minimizeormaximizea scalar function, called theobjective
  function. | 
| org.apache.commons.math3.optimization.direct | 
 This package provides optimization algorithms that don't require derivatives. | 
| org.apache.commons.math3.util | Convenience routines and common data structures used throughout the commons-math library. |
