Thanks for the attentions.
Sage can handle matrices that size, but it doesn't print out all of the entries when the matrix is larger than 19x19. If you want to print all of the entries of a larger matrix m, you can do print m.str() But, it's probably not helpful when it's that large. Here's an example showing that things do work. sage: m = random_matrix(ZZ,1000,1000) sage: m 1000 x 1000 dense matrix over Integer Ring sage: z = m - m sage: z == 0 True --Mike -- 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 URL: http://www.sagemath.org
