I don't think one would want to have multiple outputs, rather one would want to have a *single* (symbolic) vector as output. It might make more sense to simply allow symbolic vectors to be callable, passing the arguments to each of their components. - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
