Look at block_matrix: sage: A = matrix(QQ, 2, 2, [3,9,6,10]) sage: block_matrix([A, -A, ~A, 100*A]) [ 3 9| -3 -9] [ 6 10| -6 -10] [-----------+-----------] [-5/12 3/8| 300 900] [ 1/4 -1/8| 600 1000] Harald --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@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-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
