mactex-utilities: Problem with tex() and matrices.

Peter,

>   \left(\vatwothree\,\vathreeone+\vatwoone\right)\,\Satwotwo\left(x ,

>   \,\Saoneone\left(x\right)}\over{\Eaoneone}}$$

Hmm, this is strange ... I wonder why the indices are spelled out
(one, two, three) instead of being written as numerals.
What does build_info() report?

About mactex-utilities, I don't know what the problem is.
Maybe it's enough just to put the following bit in a separate file
and load it (assuming what you want is \frac instead of \over).

(defun tex-mquotient (x l r)
  (if (or (null (cddr x)) (cdddr x)) (wna-err (caar x)))
  (setq l (tex (cadr x) (append l '("\\frac{")) nil 'mparen 'mparen)
    r (tex (caddr x) (list "}{") (append '("}") r) 'mparen 'mparen))
  (append l r))

Hope this helps,
Robert
