Description
Is there a way to construct block matrices in SAGE? Not just the "block_sum", "augment" and "stack" functions. As an example, let A, B, C, D be matrices and i want to construct a matrix like E=[[A,B],[C,D]] Such a feature would be very nice. -vgermrk-

Just wanted to point out that this patch works great for me, both for block diagonal matrices and for creating block matrices from lists.

I merged all three patches into Sage 2.10.alpha3

Much expanded functionality due to discussion at http://www.mail-archive.com/sage-devel@googlegroups.com/msg08958.html
See the docstrings in the patch for many examples.
