Hi, maybe some of you have already noticed it, but I recently did several changes in the sparse modules:

Great to hear! Partially I noticed it (but I didn't follow every commit)

- the SparseMatrix class is now more versatile and simpler to use with a single API to insert elements, - the DynamicSparseMatrix has been removed (still available in unsupported/SparseExtra), - deprecated functions have been removed,

- the solvers classes moved from unsupported/ to official modules, - conservative matrix products,

I guess that solves http://eigen.tuxfamily.org/bz/show_bug.cgi?id=284 ?

- etc. You can have a look at the updated documentation: http://eigen.tuxfamily.org/dox-devel/TutorialSparse.html to get a better idea of what's there, and as usual any feedback is very much appreciated.

The example code in: http://eigen.tuxfamily.org/dox-devel/TutorialSparse.html#TutorialSparseFilling uses 3 different identifiers for the same matrix.

I think that now they are sane enough to release a first beta of the future 3.1 version of Eigen for which stable sparse modules will be the major feature.

As I asked in IRC already:

into 3.1 beta? (Or give me suggestions how to modify/improve it)

I plan to do the release on Monday. Though this is less critical for a beta release, reports of the results of the unit tests on various systems, especially with MSVC, would still be appreciated. cheers, gael
