Like #+begin_src matlab :results output clear all syms e p R g w K K2 phi=[(e + (e+p)*R^2)^((g-1)/2);((e+p)*R*sqrt(1+R^2))/(e+(e+p)*R^2)] jac=jacobian(phi,[e,p]) ltxjac=latex(jac) #+end_src This result should of course also be included in the orgfile. But then I want to export the org file to latex, such that only the results, which have been converted to latex are exported and all the matlab command should be ignored, that is in that case: ltxjac but nicely surrounded by say $. Anybody has an idea how to do this efficiently? thanks regards Uwe Brauer ^ permalink raw reply [flat|nested] 29+ messages in thread

However I just realized that I don't understand the logic of what you sent to me. So it looks like #+BEGIN_SRC emacs-lisp (defun org-babel-execute:matlab (body params) (interactive "P") (let* ((current-file (buffer-file-name)) (code (org-element-property :value (org-element-context))) (result-params (cdr (assoc :result-params params))) m-file md5-hash) (with-temp-buffer (insert code) (setq md5-hash (md5 (buffer-string)) mbuffer (format "*m-%s*" md5-hash) m-file (format "m-%s.m" md5-hash))) ;; create the file to run (with-temp-file m-file (insert code)) (let ((results (shell-command-to-string (concat "/Applications/MATLAB_R2013a.app/bin/matlab " "-nodesktop -nojvm -nosplash -nodisplay <" m-file)))) (delete-file m-file) (when results ;; strip out >> (setq results (replace-regexp-in-string ">> " "" results)) ;; remove first 10 lines that are the header. (setq results (mapconcat 'identity (nthcdr 10 (split-string results "\n")) "\n"))) (org-babel-result-cond result-params results)))) #+END_SRC That lisp function uses a m-file, but which one? When I run the lisp code in my org file (changing the path to my matlab installations path) I obtain #+RESULTS: : org-babel-execute:matlab But not what you have sent to me and I copied below namely #+begin_src matlab :results output latex clear all; syms e p R g w K K2; phi=[(e + (e+p)*R^2)^((g-1)/2);((e+p)*R*sqrt(1+R^2))/(e+(e+p)*R^2)]; jac=jacobian(phi,[e,p]); ltxjac=latex(jac); disp(ltxjac) #+end_src which I presume is your output of the lisp function? I am sorry but I am more confused than ever. I even see that I cannot (after I have executed your lisp function) execute anymore the following #+begin_src matlab :results output t=[-3 -2 1 4 6] y=[2 0 3 1 4] cs = spline(t,[0 y 0 ]) [b,c,l,k,d]= unmkpp(cs) #+end_src I tested it several times. I restart emacs open an org mode with the above matlab instructions and I can execute matlab. Then I execute your lisp code and I cannot run matlab anymore in an org buffer. What is wrong here?

You may need to add ":exports results" to the src line.

I just found out that it will not work for me since the matlab-kernel will need the python support of matlab, which requires version 2016 o later. And indeed the most annoying issue of executing matlab in an org buffer using the babel interface was the fact that it was slow since every time matlab needs to be restarted. Now that matlab-kernel thing seems to resolve the issue. However it needs a very recent version of matlab. Therefore my proposal: there exists already a matlab-shell written in lisp written by Eric Ludlam and others which does not require a restart of matlab for every call. Couldn't your code (defun org-babel-execute:matlab (body params) trying to use matlab-shell-run-command or matlab-shell-run-region? I don't understand enough of either function to try to modify it.

Ah, great, but it only works for vectors x = [1, 2, 3, 4, 5] fprintf('|%d', x) For matrices it has to be sprintf %% A=[1 2 3; 4 5 6; 7 8 9] sprintf('|%d |%d |%d|\n',A') ^ permalink raw reply [flat|nested] 29+ messages in thread
