Improvement on matlab-emacs

Modification to matlab-cellbreak-face

Current cvs code for matlab.el does not handle cellbreak-face correctly. It cannot distinguish between %% and %%%%, but matlab-shell-run-cell can function well. But fontifying not well is still annoying, so we need to modify it. In matlab.el, find the following lines to modify from:

;; Cell mode breaks get special treatment
'("^\\s-*\\(%%[^\n]*\n\\)" (1 matlab-cellbreak-face append))

Change it to:

;; Cell mode breaks get special treatment
'("^\\s-*\\(%%[^%\n]*\n\\)" (1 matlab-cellbreak-face append))

Evaluate cell and advance (C-S-return)

In MATLAB editor, we can press C-S-return to perform "evaluate cell and advance" function. Minor modification to matlab.el can make it happen. You can just add the following code snippet to your .emacs file.

(require 'matlab-load)
(defun matlab-goto-next-cell ()
  (interactive)
  (re-search-forward "^%%[^%\n]"))

(require 'matlab)
(define-key matlab-mode-map [(meta control F)] 'matlab-goto-next-cell)
(defun matlab-run-cell-and-go ()
  (interactive)
  (progn
    (save-excursion
      (matlab-shell-run-cell))
    (matlab-goto-next-cell)))
(define-key matlab-mode-map [(meta shift return)] 'matlab-run-cell-and-go)

The example for running matlab cell mode is like this:

a = [1,2,3];

c = [4,5,6];

%% This is first cell

d = a * c';

%%%% This is not a cell

b = [3,2,1];

%% Another cell

c = a + b;

kkk

After pressing three <C-S-return>, the matlab-shell screen will look like:

                            < M A T L A B (R) >

Okay, now matlab-emacs for me is more convenient right now. Hope you enjoy it!
