Is there a reason why matrix(F,[[]]) and matrix(F,[]) should return different things?
sage: F=GF(3) sage: a=matrix(F,[[]]) sage: b=matrix(F,[]) sage: a==b False sage: a.rows() [()] sage: b.rows() [] sage: a.block_sum(matrix(F,[[1,0],[0,1]])) [0 0] [1 0] [0 1] sage: b.block_sum(matrix(F,[[1,0],[0,1]])) [1 0] [0 1] Thanks, Jason --~--~---------~--~----~------------~-------~--~----~ 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/ -~----------~----~----~----~------~----~------~--~---
