Hipparchus

License

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.

Documentation

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.

Where can I get the latest release?

You can download source and binaries from our download page.

Alternatively you can pull it from the central Maven repositories using pom.xml settings:

<properties>
  <!-- change the Hipparchus version number to the one suiting your needs -->
  <myprojectname.hipparchus.version>1.6</myprojectname.hipparchus.version>
</properties>

<dependency>

If your project previously depended on Apache Commons Math and you want to switch to Hipparchus, you can also add the temporary migration jar

<dependency>
  <groupId>org.hipparchus</groupId>
  <artifactId>hipparchus-migration</artifactId>
  <version>${myprojectname.hipparchus.version}</version>
</dependency>

Contributing

There are some guidelines which will make applying contributions easier for us. Please read through our contributing guidelines.

To contact us, there are (temporarily) two communication channels. The recommended one is a shared forum where several categories are dedicated to Hipparchus. The oldedr one is a developers mailing list. Beware that the mail-based channel is buggy (read loses messages) and unmaintained, so the forum is probably a safer channel as of release 1.6.
