I didn't manage to get your (Nicolas') or my own attempt working
correctly for exporting matrices.  I still think it would be nice.

I tried to use the regexp=20
   (not (string-match "|[\\+-]+|"  table))
to identify tables without heading separators, but it didn't work
properly.=20

Thinking about it, it might be nice to be able to specify table export
function more generally.  For instance, I might have a matrix with
labels (in LaTeX a bordermatrix or kbordermatrix).  Likewise, it might
also be nice to specify a header argument to tables s.t. I can specify
a name, e.g.

#+NAME: P=20
#+TBLOPTIONS: :prefix "P=3D" :type matrix
| a| b|
| c| d|

would export to=20
\[P=3D\begin{bmatrix}a&b\\c&d\end{bmatrix}\]

--=20
