Do you expect this to be fixed somewhere in maxima and to produce the output always with \begin{pmatrix} ... \end{pmatrix}?
  
  
  Maxima defines function for tex output. Function `tex-matrix` defined in maxima source file `mactex.list:662`. It looks like this:
  
    (defun tex-matrix(x l r) ;;matrix looks like ((mmatrix)((mlist) a b) ...)
      (append l `("\\pmatrix{")
    	  (mapcan #'(lambda(y)
    		      (tex-list (cdr y) nil (list "\\cr ") "&"))
    		  (cdr x))
    	  '("}") r))
  
  As you see, the function generate outdated tex output. And I think that for modern LaTeX it should update to '\begin{pmatrix}...\end{pmatrix}. So, if I push this changes to maxima and the changes be accepted, function tex-matrix redifinition in `cantor-initmaxima.lisp` can be removed.
