Hi
I decided to start a new thread, since I made some progress and it seems
there are at least two ways to execute matlab from an org buffer and
insert the result back into that buffer.
1. Using the python engine matlab ships (I am not describing the
setup now)
Disadvantage
a. Not all matlab releases support all ptyhon versions. For
example ptyhon 3.5 is only supported till 2019a
b. It takes some time for the python engine to start
Advantage
a. The format of the result is very nice.
2. Using the matlab-shell itself (thanks @Martin for pointing this
out)
Test Configuration:
a. Start emacs -Q
b. Load the following file
--8<---------------cut here---------------start------------->8---
(setq load-path (cons (expand-file-name
"~/emacs/site-lisp/packages/src/Matlab/HG-Git/matlab-sf-hg") load-path))
(load-file "/home/oub/emacs/init/custom-init-faces.el")
(require 'company-matlab-shell)
(require 'org)
(require 'gdb-mi)
(autoload 'matlab-mode "matlab" "Enter Matlab mode." t)
(setq auto-mode-alist (cons '("\\.m\\'" . matlab-mode) auto-mode-alist))
(autoload 'matlab-shell "matlab" "Interactive Matlab mode." t)
(org-babel-do-load-languages
'org-babel-load-languages '(
(C . t) ; enable processing C, C++, and
D source blocks
(matlab . t)
;;(perl . t)
(octave . t)
(org . t)
(python . t)
(plantuml . t)
(shell . t)
))
(setq org-babel-default-header-args:matlab
'((:results . "output") (:session . "*MATLAB*")))
--8<---------------cut here---------------end--------------->8---
And load ob-octave-fix.el
https://github.com/karthink/.emacs.d/blob/master/plugins/ob-octave-fix.el
Then the following code can be executed in a org buffer
#+begin_src matlab :results output latex :exports results :eval
never-export :wrap latex
clear all
x = [1, 2, 3, 4, 5];
disp(sprintf('|%d', x))
#+end_src
#+RESULTS:
#+begin_latex
x = [1, 2, 3, 4, 5];
disp(sprintf('|%d', x))
|1|2|3|4|5
#+end_latex
#+begin_src matlab :results output latex :exports results :eval
never-export :wrap latex
clear all
x = [1, 2, 3, 4, 5];
disp(sprintf('|%d', x))
#+end_src
#+RESULTS:
#+begin_latex
|1|2|3|4|5
#+end_latex
That already indicates that the formatting needs care, moreover
=fprintf= is not supported
#+begin_src matlab :results output latex :exports results :eval
never-export :wrap latex
clear all
x = [1, 2, 3, 4, 5] ;
fprintf('|%d', x)
#+end_src
#+RESULTS:
#+begin_latex
#+end_latex
So I need to investigate this a bit more.
In summary: the second solution works surprisingly well and is faster
than the python solution, but the formatting seems to me more restricted
as in the python case.
Any comments?
Has anybody tried this out?
@John you talked about such feature in the past.
Can you confirm this behavior?

Uwe
