Re: [eigen] News on sparse modules and 3.1 beta 1 on Monday

[Pavel Holoborodko <pavel@xxxxxxxxxxxxxxx>]

One more thing, compilation for all cwiseop_X failed because of error:

    c:\temp\eigen.3.1\eigen\src/Eigen2Support/CwiseOperators.h(103): error C2244: 'min' : unable to match function

      definition to an existing declaration

Hi Gael,

I've compiled & tested latest Eigen using MSVC 2010 for x86. 

I am not sure whether all sparse-related tests run (I don't have SuiteSparse nor SuperLU).

Tests failed:

  41 - cwiseop_1 (Not Run)

  42 - cwiseop_2 (Not Run)

  43 - cwiseop_3 (Not Run)

  44 - cwiseop_4 (Not Run)

  45 - cwiseop_5 (Not Run)

  46 - cwiseop_6 (Not Run)

 442 - qtvector (OTHER_FAULT)

 487 - eigen2support_1 (Not Run)

 488 - eigen2support_2 (Not Run)

 489 - eigen2support_4 (Not Run)

 490 - eigen2support_5 (Not Run)

 491 - eigen2support_6 (Not Run)

 531 - autodiff (Not Run)

 558 - sparse_extra_1 (Failed)

 559 - sparse_extra_2 (Failed)

"Not run" - means compilation of the test failed. 

Both sparse_extra_1(2) tests failed with the same assertion: 

558/580 Testing: sparse_extra_1

Feel free to teach me on how to do tests for sparse modules if I missed something/or want more information.

Hi,

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

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.

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
