Hi I am on ubuntu 16.04 with python 3.5 and 2.7 in the past I have used successfully the matlab python kernel for 3.5
Using more or less this: sudo apt-get install python3-setuptools sudo -H python3 -m pip install jupyter 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/python sudo -H python3 setup.py install ** Start the engine Run /usr/bin/python3 in the python prompt: import matlab.engine eng = matlab.engine.start_matlab() the eng command needs some time to run. When finished run now #+BEGIN_SRC emacs-lisp (setq org-confirm-babel-evaluate nil) ;;; 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 "/usr/bin/python3") ;(setq python-shell-interpreter "/usr/bin/python2.7") ;; 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 However I am forced to use matlab 2019b, which is not longer compatible with python 3.5, but according to their documentation with 2.7, so I repeated the steps above using python-2.7 instead of 3.5 And of course ;(setq python-shell-interpreter "/usr/bin/python3") (setq python-shell-interpreter "/usr/bin/python2.7") But when I try to execute in an org file #+begin_src matlab :results output latex :exports results :eval never-export :wrap latex x = [1, 2, 3, 4, 5]; fprintf('|%d', x) #+end_src Emacs shows me that is he is working and working and finally I have to interrupt the process, I also don't see any error stack. Anybody has successfully used the above configuration with python 2.7? Thanks Uwe Brauer
