These are the usage notes for matlabShell.exe, version 1.1, a matlab shell engine suitable for use with Windows XP+.
matlabShell.exe can be used standalone in a command window, and many installation mysteries can be cleared up by doing so, thereby helping to determine whether any problems are with the shell installation or with the matlab.el installation.
Follow matlab-mode instructions for details. Your emacs initialization should have something like this in it:
;; Load CEDET.
;; See cedet/common/cedet.info for configuration details.
;; IMPORTANT: For Emacs >= 23.2, you must place this *before* any
;; CEDET component (including EIEIO) gets activated by another
;; package (Gnus, auth-source, ...).
(load-file "d:/dev/emacs/cedet/common/cedet.el") ;; cedet-devel-load.el")
;; Replace path below to be where your matlab.el file is.
(add-to-list 'load-path "d:/dev/emacs/matlab-emacs")
(load-library "matlab-load")
;; Change path
(setq matlab-shell-command "c:/Programs/matlabshell/matlabshell.exe")
(setq matlab-shell-command-switches '("10000" "20000"))
;; the following is for non-session based evaluations
(setq org-babel-matlab-shell-command "c:/Programs/matlabshell/matlabshell.cmd")
;; Have libeng.dll on your PATH or use the following
(setenv "PATH" (concat "C:/PROGRA~1/MATLAB/R2011a/bin/win32;" (getenv "PATH")))

'((matlab . t) (octave . t)
))
(setq org-babel-default-header-args:matlab
'((:results . "output") (:session . "*MATLAB*")))If you want to recompile and link this code do it with make provided you have gcc installed. Otherwise use linkit.bat if you have MS VC++ (Express) installed. lcc shipped with Matlab has issues with stdout buffering.
Matlab code blocks are served by ob-octave.el . Unfortunately Octave and Matlab deviated quite a bit in their development. Also ob-octave has not been updated for quite a while and does not support some org-babel properties. The followin patch can help.
