Iridium is the numerical foundation of Math.NET, aiming to provide commonly used mathematical elements for scientific numerical computations. It offers the infrastructure for basic numerics, linear algebra, random generators and distributions, integral transformations, etc. Iridium is self-contained, it does not depend on external libraries like Intel MKL, BLAS or LAPACK.
Math.NET Iridium is part of the Math.NET initiative. Available for free under the LGPL License.
Math.NET Iiridium has been merged with dnAnalytics into Math.NET Numerics, replacing both. Iridium is therefore discontinued.
If you have Github for Windows installed you can click here to fetch the sources, otherwise clone it in the shell with:
$ git clone git://github.com/mathnet/mathnet-iridium.git
We use the Fork & Pull model, as common for Github projects. Instead of asking for permission, simply fork the project on Github, commit your changes in a separate branch and send a pull request to one of the maintainers. A maintainer will then merge your changes back to mainline, or work together with you on the changes if they are not acceptable yet. Only maintainers can write to mainline, but anyone can contribute - don't ask, do!
Of course other contributions are very welcome as well, being it some publicity, more interesting code samples, code reviews, extending the documentation or even just some ideas. We're also looking for maintainers.
