### sagetex formating matrices

Hello all,

I would like to have sagetex producing matrices with the columns centered. If was writing this by hand, I would do
`\begin{bmatrix*}[c] ... \end{bmatrix*}`

From my XXX.sout file, I see the result `\begin{array}{rrr} ... \end{array}`

. Is there a way to control this? Either playing at the sage level directly or by controlling sagetex?

Thanks!
