## Uses of Class
org.apache.commons.math3.util.Pair

Packages that use Pair
org.apache.commons.math3.analysis.integration.gauss | Gauss family of quadrature schemes.
org.apache.commons.math3.distribution | Implementations of common discrete and continuous distributions.
org.apache.commons.math3.optim | Generally, optimizers are algorithms that will either `minimize` or `maximize` a scalar function, called the `objective function`.
org.apache.commons.math3.optimization | All classes and sub-packages of this package are deprecated.
org.apache.commons.math3.util | Convenience routines and common data structures used throughout the commons-math library.
