Hi
I think I solved the issue. Here are some instructions which might be
useful.
ob-ipython seems to work with python3 not 2.X
So the first thing is to run (Ubuntu/Debian)
* Installation of jupyter and the matlab_kernel
sudo apt-get install python3-setuptools
sudo -H python3 -m pip install jupyter
% there is a conflict with the pexpect package as shipped with
Debian/Ubuntu.
sudo apt-get remove python3-pexpect
sudo -H python3 -m pip install pexpect
sudo -H python3 -m pip install matlab_kernel
** Install the python API for matlab.
MATLABROOT=/usr/local/MATLAB/R2016b
Cd $MATLABROOT/extern/engines/
sudo -H python3 setup.py install
** Start the engine Run
Python3
import matlab.engine
eng = matlab.engine.start_matlab()
Configure babel
#+BEGIN_SRC emacs-lisp
(setq org-confirm-babel-evaluate nil) ;don't prompt me to confirm everytime I want to evaluate a block
;;; display/update images in the buffer after I evaluate
(add-hook 'org-babel-after-execute-hook 'org-display-inline-images 'append)
(add-to-list 'org-src-lang-modes '("matlab" . matlab))
(setq python-shell-interpreter "python3")
;; set default headers for convenience
(setq org-babel-default-header-args:matlab
'((:results . "output replace")
(:session . "matlab")
(:kernel . "matlab")
(:exports . "code")
(:cache . "no")
(:noweb . "no")
(:hlines . "no")
(:tangle . "no")))
(defalias 'org-babel-execute:matlab 'org-babel-execute:ipython)
(defalias 'org-babel-prep-session:matlab 'org-babel-prep-session:ipython)
(defalias 'org-babel-matlab-initiate-session 'org-babel-ipython-initiate-session)
#+END_SRC
Then use the following example
#+begin_src matlab :results output latex :exports results :eval never-export :wrap latex
x = [1, 2, 3, 4, 5];
fprintf('|%d', x)
#+end_src
That is now really fast.
Regards
Uwe Brauer
