Hmm, with my limited python knowledge I don't think it is doable :-) I can't find myself in sage/matrix code, and I fear those .pyx/.pxd files... I think I will just point to this email if I receive bug reports about this problem, and leave as is for now, as packaging a full alternate maxima in the sagemath package is overkill... > Thanks, > > Jason > > > > -- > Jason Grout Thanks, Paulo --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
