View source for News:Eigen 3.1.0-alpha2 released with support for Intel MKL!

Eigen 3.1.0-alpha2 has been released on February 6, 2012.

The source archive is at:
http://bitbucket.org/eigen/eigen/get/3.1.0-alpha2.tar.bz2

The key novelty of this alpha release is the possibility to fallback to [http://eigen.tuxfamily.org/Counter/redirect_to_mkl.php Intel MKL] (or another external BLAS library) for a couple of operations including matrix products (BLAS L2/L3), dense matrix decompositions (LAPACKE), and math array operations (via the Intel VML). These completely '''optional''' backends can be enabled through some compile-time preprocessor directives as explained in the respective [http://eigen.tuxfamily.org/dox-devel/TopicUsingIntelMKL.html manual page].
In the same vein, this version also brings support for the Intel MKL PARDISO direct sparse solver.
Recall that [http://eigen.tuxfamily.org/Counter/redirect_to_mkl.php Intel MKL] is '''proprietary''' software (see this [http://eigen.tuxfamily.org/dox-devel/TopicUsingIntelMKL.html notice]).

This new version also provides improved performance for small matrix-matrix products, support for rank updates/downdates in LDLt and LLT, a new fast sparse matrix assembly interface from a random list of triplets, and many other minor improvements and fixes.
