Exporting matrices to lateX generates outdated code:

! Package amsmath Error: Old form `\pmatrix' should be \begin{pmatrix}.
See the amsmath package documentation for explanation.

Instead of
\pmatrix{<content>}
cantor should generate
\begin{pmatrix}<content>\end{pmatrix}
to work with current versions of amsmath.
