## Package org.apache.commons.math.analysis Description

Parent package for common numerical analysis procedures, including root finding, function interpolation and integration. Note that the optimization (i.e. minimization and maximization) is a huge separate top package, despite it also operate on functions as defined by this top-level package.

Functions interfaces are intended to be implemented by user code to represent their domain problems. The algorithms provided by the library will then operate on these function to find their roots, or integrate them, or ... Functions can be multivariate or univariate, real vectorial or matrix valued, and they can be differentiable or not.
