;;; Commentary:

;; Functions that are common to org-babel support for matlab and
;; octave are in org-babel-octave.el

;;; Requirements:

;; Matlab

;; matlab.el required for interactive emacs sessions and matlab-mode
;; major mode for source code editing buffer
;; http://matlab-emacs.sourceforge.net/

;;; Code:
(require 'matlab)
(require 'ob-octave)
