| Package | Description | 
|---|---|
| org.apache.commons.math3.analysis | 
      Parent package for common numerical analysis procedures, including root finding,
      function interpolation and integration. | 
| org.apache.commons.math3.analysis.differentiation | 
   This package holds the main interfaces and basic building block classes
   dealing with differentiation. | 
| org.apache.commons.math3.optimization.general | This package provides optimization algorithms that require derivatives. | 
| Modifier and Type | Method and Description |
