Re: [Matlab-emacs-discuss] Emacs hangs with a line

[Tak K. <tak...@gm...>]

I revered to matlab-mode-20180125.1810 from matlab-mode-20180928.1526 and
now it works.  I setup my Emacs in following manner.

(setq package-load-list '((matlab-mode "20180125.1810") all))

I also found that in an emergency case, following works.

(setq octave-comment-char ?%)
(add-to-list 'auto-mode-alist '("\\.m\\'" . octave-mode))
