success 5393 Eigen 2007-05-15T14:01:28Z 2009-11-27T09:44:09Z Eigen is a C++ template library for linear algebra (vectors, matrices, and related algorithms). * It supports tiny, dense, and sparse matrices (the latter is still experimental), fully integrated with one another. * It takes full advantage of expression templates to provide a great API. For example, m.row(i)+=m.row(j) just works. * Expression templates are also the basis for many optimizations: automatic determination of which temporaries to remove, and intelligent explicit vectorization (SSE and ALtiVec). * Performance is on par with the best BLAS implementations (see http://eigen.tuxfamily.org/index.php?title=Benchmark). * It keeps in mind the real needs of apps, for example the geometry features needed for 3D graphics http://eigen.tuxfamily.org http://eigen.tuxfamily.org/index.php?title=Main_Page#Download http://bits.ohloh.net/attachments/7340/Eigen_Silly_Professor_64x64_med.png http://bits.ohloh.net/attachments/7340/Eigen_Silly_Professor_64x64_small.png 12 3 773564 773564 5393 2009-11-27T09:44:08Z 2009-11-27T09:41:58Z 2007-05-01T00:00:00Z 2009-11-01T00:00:00Z 31 68769 44 C++ gpl2_or_later GNU General Public License 2.0 or later lgpl3 GNU Lesser General Public License 3
