However,when I query a vector or matrix “test”
matlab>test
matlab wraps the display at column 70

That seemed like a good clue and it suggested this was more of a matlab inside emacs problem than an emacs problem, but I haven’t figured out how to configure emacs to understand the terminal width when it’s running inside emacs..
I’ve tried
things like
(defcustom matlab-fill-fudge-hard-maximum 150
inside of matlab.el
without success.

Can anyone help ?

Thx,

You can specify which options to send to matlab by adding

(custom-set-variables
 '(matlab-shell-command-switches '("-nodesktop -noslpash -nojvm")))

to your .emacs.

It’s been 5 month but hope you’ll come across this/figured it out.

(defcustom matlab-shell-command "matlab"
....
 to be
(defcustom matlab-shell-command "/Applications/MatLab/MATLAB_R2011a.app/bin/matlab"
....

I was able to get it to run properly

I didn’t even find a proper website to download the matlab.el – what do i miss here ?

I’m trying to use emacs 23.3.1 (cygwin) with matlab and matlab-shell doesn’t work. I suppose this is the same reason as stated above in general for any Windows user.

I echo George’s feelings exactly: I will never go back to using a separate editor/IDE for every type of development I do, and the Matlab editor is not the answer. Hmm.., GNU-Octave has a nice emacs mode…

–Randy

if usejava(‘jvm’), com.mathworks.services.Prefs.setBooleanPref(‘EditorGraphicalDebugging’, false); end

In my .emacs file, I put:

(setq matlab-shell-command-switches ‘(“-nosplash” “-nodesktop” “-nojvm”))

but it doesn’t work.

Any idea how I should deal with it? Thank you so much!

Until you bring EmacsLink back or at provide least a public API that allows to reimplement EmacsClient I’ll try everything to avoid Matlab!

edit file.m

a Command Prompt window would open up with an error message saying:

'"emacsclient -a emacs -n"' is not recognized as an internal or external command, operable program or batch file.

I knew that it wasn’t an issue with emacsclient because I could open the file from the Windows command prompt without any errors.

After snooping around in the edit.m file, I figured out that the problem stemmed from the fact that edit.m wraps calls to user-supplied external editors in double quotes “in case it contains spaces.” Of course, when you’re trying to use the -a or -n option with emacsclient, this wrapping in double quotes confuses Windows, which tries to interpret the entire string as an executable rather than parsing it into an executable (emacsclient) plus arguments (-a emacs -n).

I was able to make it work seamlessly by changing lines 220-227 in the openExternalEditor function from this:

if ispc
    % On Windows, we need to wrap the editor command in double quotes
    % in case it contains spaces
    if nargin == 0
        system(['"' editor '" &']);
    else
        system(['"' editor '" "' file '" &']);
    end

to this:

if ispc
    % We don't want to use double quotes since our editor
    % command contains arguments, and the & is unnecessary
    if nargin == 0
        system(editor);
    % but we do still need to wrap the file in double
    % quotes, in case it includes a path with folder names
    % that have spaces...
    else
        system([editor ' "' file '"']);
    end

I’m not sure whether this would be an issue for other versions of Matlab on Windows, but I figured I’d pass along the info in case it helps someone else!

emacsclient -a emacs -n

So if there’s no current emacs server, it’ll open a new emacs window.
