Can I get a matrix to show with brackets instead of parentheses?
I'm using Sage and SageTeX to make worksheets and quizzes for my Linear Algebra course. I'd like my presentation to match the book's, and the book uses brackets around its matrices instead of parentheses. Is that doable? Is there a way, for example, to get latex(A) to generate
\left[\begin{array}{rrr} 6 & 6 & 1 \\ 7 & 0 & 6 \\ 4 & -7 & -7 \end{array}\right]instead of
\left(\begin{array}{rrr} 6 & 6 & 1 \\ 7 & 0 & 6 \\ 4 & -7 & -7 \end{array}\right)for some matrix A.
I found some discussion of the matter [on google](https://groups.google.com/forum/#!topic/sage-support/pP_DjwoYUGs), but I don't think I'm savvy enough to edit latex.py, especially since a search of my computer shows 9 seperate files called latex.py.
By the way, awesome to use SageTeX for this - a very good use of it.
