Hi, I get this:
sage: R=IntegerModRing(8) sage: m=matrix(R,2,[2,1,3,3]);m.det() sage: m.inverse() Traceback (most recent call last): ... TypeError: self must be an integral domain. sage: m^-1 Traceback (most recent call last): ... TypeError: self must be an integral domain. Actually, R(3)^-1 produces an error message. I use Sage 3.4. Is someone implementing the inverse operation in integer mod rings? --~--~---------~--~----~------------~-------~--~----~ 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 URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
