I don't think so but it should be relatively easy to add (hint, hint :)) First, I'd check whether Singular has such a function and wrap that. If Singular doesn't have this function readily available, then one would have to write it oneself. Cheers, Martin PS: I would do it, but I am still stuck with thesis related stuff. -- name: Martin Albrecht _pgp: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8EF0DC99 _otr: 47F43D1A 5D68C36F 468BAEBA 640E8856 D7951CCF _www: http://www.informatik.uni-bremen.de/~malb _jab: [email protected] --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
