GluCat ( http://glucat.sf.net ) currently uses uBLAS, which is part of Boost. I'm looking at Eigen ( http://www.macresearch.org/interview-eigen-matrix-library http://eigen.tuxfamily.org/ http://eigen.tuxfamily.org/index.php?title=Benchmark ) as a possible replacement. For GluCat integration in

I need a convenient matrix class for some numerical work. SciPy doesn't accept GPL code and besides I heavily dislike the NumPy matrix class. So why not put my efforts into improving Sage (or at least write something Sage-compatible for myself)... In particular I need to Cholesky-factor Hermiti
