Does this version contain the bugfix you gave me in IRC about 3 weeks ago?

If I remember correctly you did create a SAGE package, but I do believe that there still is/was a problem with systems with parameters, i.e. when the indeterminates are caputalized. I am not sure if SAGE can do that yet. > Martin > Cheers, Michael --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
