Re: [Matlab-emacs-discuss] executing matlab in org mode files (using the matlab-shell)

[Eric L. <Eri...@ma...>]

Ah,  sorry I can't be more help.  It has been many years since I worked on that code, and I don't use Emacs much anymore.  There are accommodations in the function's I referenced for the ML command line to make sure it doesn't interrupting anything a user might be typing in that would be important for your use case.

It might be worth trying the Matlab help stuff in matlab-mode/matlab-shell to see if it still works.  This is code that will call help, and put output into a separate buffer.  I haven't tested it in ages, so if it isn't working in ML shell, that might explain any issues you're bumping into with org mode.

Yeah I tried to debug it and to understand its structure. The matlab-shell-command is, at least for me, maybe the most complex part of the code. On the other hand the crucial parts of John's code are the lines

      (let ((results (shell-command-to-string
  		    (concat
  		     "/usr/local/bin/matlab "
  		     "-nodesktop -nojvm -nosplash -nodisplay <"
  		     m-file))))

So I hoped somebody with a better understanding of the matlab-shell-command could give me a hint, but it seems that the merge between John's code and matlab-shell is much more complicated.

Yes I did and John's code does precisely this. I asked the same question on the orgmode list and John replied. The only problem with his code is that it uses the command line matlab command and so starts every time matlab, when the code is executed.

No that is ok, I hoped orgmode could take that part as well but all my attempts failed.
