;;
;;; Commentary:
;;
;; This major mode for GNU Emacs provides support for editing MATLAB dot-m
;; files. It automatically indents for block structures, line continuations
;; (e.g., ...), and comments.
;;
;; Additional features include auto-fill including auto-additions of
;; ellipsis for commands, and even strings. Block/end construct
;; highlighting as you edit. Primitive code-verification and
;; identification. Templates and other code editing functions.
;; Advanced symbol completion. Code highlighting via font-lock.
;; There are many navigation commands that let you move across blocks
;; of code at different levels.
;;
;; Lastly, there is support for running MATLAB in an Emacs buffer,
;; with full shell history and debugger support (when used with the db
;; commands.) The shell can be used as an online help while editing
;; code, providing help on functions, variables, or running arbitrary
;; blocks of code from the buffer you are editing.
;;; Finding Updates:
;;
;; The latest stable version of matlab.el can be found on MATLAB Central:
;;
;; Catagory:
;; http://www.mathworks.com/matlabcentral/fileexchange/loadCategory.do?objectId=19&objectType=Category
;; This File
;; http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=104&objectType=file
;;
;; Older versions of matlab.el can be found in as matlab.el.1.10.1
;; for emacsen that do not have the latest additional utilities such
;; as tempo and derived.
;;; Installation:
;;
;; Put the this file as "matlab.el" somewhere on your load path, then
;; add this to your .emacs or site-init.el file:
;;
;; (autoload 'matlab-mode "matlab" "Enter MATLAB mode." t)
;; (setq auto-mode-alist (cons '("\\.m\\'" . matlab-mode) auto-mode-alist))
;; (autoload 'matlab-shell "matlab" "Interactive MATLAB mode." t)
;;
;; User Level customizations (You need not use them all):
;; (setq matlab-indent-function t) ; if you want function bodies indented
;; (setq matlab-verify-on-save-flag nil) ; turn off auto-verify on save
;; (defun my-matlab-mode-hook ()
;; (setq fill-column 76)) ; where auto-fill should wrap
;; (add-hook 'matlab-mode-hook 'my-matlab-mode-hook)
;; (defun my-matlab-shell-mode-hook ()
;; '())
;; (add-hook 'matlab-shell-mode-hook 'my-matlab-shell-mode-hook)
;;
;; If you are using a version of MATLAB with the Desktop enabled,
;; you may need to add this:
;;
;; (setq matlab-shell-command-swithes '("-nojvm"))
;;
;; Please read the mode help for matlab-mode for additional
;; configuration options.
;;
;; Syntax highlighting:
;; To get font-lock try adding this for older emacsen:
;; (font-lock-mode 1)
;; Or for newer versions of Emacs:
;; (global-font-lock-mode t)
;; To get hilit19 support try adding:
;; (matlab-mode-hilit)
;;
;; This package requires easymenu, tempo, and derived.
;; This package will optionally use custom, shell, and gud.
;; This package supports language specific extensions in imenu, func-menu,
;; speedbar, font-lock, and hilit19.
;;; Mailing List:
;;
;; A mailing list has been set up where beta versions of matlab.el are
;; posted, and where comments, questions, bug reports, and answers to
;; questions can be sent.
;;
;; To subscribe send email to "lists@mathworks.com" with a body of:
;; "subscribe matlab-emacs"
;; to unsubscribe, send email with the body of: "unsubscribe matlab-emacs"
