Hi
Could use perfectly well the python-matlab engine from within emacs org
mode in Ubuntu 16.04, python 3.5 and matlab 2019b.
Now I am using
1. Macos 10.15 (catalina),
2. Matlab2019b. (That only support python 2.7, 3.6, 3.7 but not 3.8,
which the MacOs ships.
3. So I installed fink (and python 3.7.)
4. The installation of the python engine.
a. In /Applications/MATLAB_R2019b.app/extern/engines/python I run
b. sudo /opt/sw/bin/python3.7 setup.py install
c. The installation seem fine
5. Setting up emacs: my setting is now slightly different:
#+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 "/opt/sw/bin/python3.7")
;; 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
Now, I run as an 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
But I obtain now the unexpected error

I know that there some MaCOS users here in the list:
Any idea what went wrong.
Any help is strongly appreciated, since I don't have access to my Linux
machine fro the coming days.
