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.
