The main goal of the Sage project is to create a free, open source, viable alternative to Magma, Maple, Mathematica, and Matlab. Everything else is secondary. I of course do wish Sage could do some of the sorts of things you ask about above. But that is not the "mission statement" of the project. -- William -- William Stein Professor of Mathematics University of Washington http://wstein.org -- 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
