The Hipparchus project is a library of lightweight, self-contained mathematics and statistics components addressing the most common problems not available in the Java programming language.
More information can be found on the homepage. The JavaDoc can be browsed. Questions related to the usage of Hipparchus should be posted to the users mailing list.
