I have not tested it, but I think Ruby-GSL offers that. http://www5d.biglobe.ne.jp/~ytsune/Ruby-GSL/ GSL_Matrix#SV_decomp Generally, if doing linear Algebra madness (blas) and speed is an issue, I would recommend linking gsl with the atlas lib. http://math-atlas.sourceforge.net/ Good luck, -A. ---------------------------------------- Armin Roehrl, http://www.approximity.com We manage risk "In the long run, we're all dead." --Maynard Keynes First European Ruby conference, 21-22/6, Karlsruhe http://www.approximity.com/ruby/euruko
