I've done a lot of linear algebra benchmarking in the last couple of months and I believe there are three high-performance C++ linear algebra libraries: Eigen, already mentioned by Hans, Armadillo, and Blaze. Blaze developers present several benchmarks on their website: https://bitbucket.org/blaze-lib/blaze/wiki/Benchmarks https://bitbucket.org/blaze-lib/blaze/wiki/Benchmarks

It looks like whoever makes the benchmarks wins ;) Since Eigen3 does much worse in these benchmarks, I wonder whether the comparison is fair. I cannot imagine a good reason why Eigen is much faster than uBlas in their own benchmarks and much slower than uBlas in the benchmarks shown by Blaze. Best regards, Hans
