Hi, are you talking about sparse or dense systems? > i reading this article, but i dont understand > > http://ask.sagemath.org/question/467/solve-large-system-of-linear-equations > -over-gf2 Note that 20,000 x 20,000 isn't large for dense matrices over GF(2), you can do this in a few seconds on a modern computer. However, Sage currently does not provide an interface to the fast code we have in M4RI, hence it will appear much slower than it should (it's my fault btw.). Someone should implement it and send us a patch :) cf. solve.h in M4RI: http://m4ri.sagemath.org/doxygen/solve_8h.html Cheers, Martin -- name: Martin Albrecht _pgp: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8EF0DC99 _otr: 47F43D1A 5D68C36F 468BAEBA 640E8856 D7951CCF _www: http://martinralbrecht.wordpress.com/ _jab: martinralbre...@jabber.ccc.de -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
