Hi!

I am happy to announce the release of hmatrix-0.16, a Haskell package for matrix computations and numeric linear algebra.

New features:

- BSD3 license. The modules depending on GSL have been moved to a new package hmatrix-gsl (GPL). Now hmatrix depends only on BLAS/LAPACK.

- Simpler reexport modules with improved documentation and usage examples. There are a few API changes but the traditional modules are also exposed for backwards compatibility.

- Alternative interface using type-level literals for static dimension checking and inference (work in progress).

- Initial support for sparse linear systems.

- Minor improvements and bug fixes (see the changelog for details).

Some examples: http://dis.um.es/~alberto/hmatrix/hmatrix.html

Suggestions, contributions, and bug reports are welcome.

Thanks! Alberto

It is great to see an example page: I have tried to use hmatrix in the past for what should have been simple matrix/vector multiplication/addition but quickly became frustrated unable to figure out how to use it so I ended up writing my own (only needed few operations to try something out).

I suggest that you put the link to that page in the description of the package so it shows on Hackage, on this[1] page.

Thanks!

Secondly, I note that some modules (not all) such as Numeric.Container[2] give the missing documentation page when clicked on. Is this intentional? If I click back to something like version 0.14.x and click on Numeric.Container, I get documentation as I would expect.

Those modules are exposed for backwards compatibility but don't provide a good documentation structure. Their haddock pages are now hidden in the documentation locally generated by cabal install. We should only see four better organized reexport modules. For some reason the {-# OPTIONS_HADDOCK hide #-} pragma works in a different way in the Hackage server and all exposed modules are shown, making the online documentation even more confusing than before :(
