matlab script editing

Question

I would like to edit matlab scripts in two cases

(1) In matlab Command window running in a linux terminal, how to create and edit a script file? use

Answer 1

The matlab-emacs project at http://matlab-emacs.sourceforge.net/ is a slightly more up-to-date version of the Emacs scripts available in the EmacsLink directory that comes with MATLAB. It is OK to use the matlab-emacs project files with the EmacsLink files that comes with MATLAB. The "modulename" is "matlab-emacs".

I made a blog post about how to use Emacs with MATLAB in more recent versions of MATLAB where the EmacsLink support was dropped. You can read it here:

The scripts here show how to tweak MATLAB to to use "emacsclient" so that files are pulled up in an already running Emacs.

EDIT:

The build system is a bit imperfect with a partial download. The fact that matlab-publish didn't compile is not critical.

The matlab-emacs code from CVS includes a toolbox directory with some M code in it. When you run that code, it should setup MATLAB to use emacsclient as the editor. I wrote emacsinit.m against the most recent MATLAB, so you may need to edit it with older MATLABs that don't support all features.

To run emacsclient from matlab-shell, the path should be setup automatically, and it should run emacsclient automatically. If you don't use matlab-shell, you will need to add that directory to your MATLAB path, then call emacsinit.

If it doesn't work for calls to edit, then I'd guess an older MATLAB doesn't have the same configuration features. You can start MATLAB once with the desktop enabled, and use the Preferences dialog to specify your external editor as emacsclient -n.
