Thanks ok the whole message you sent me I can now copy into a org file and export it to latex, very nice. 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? Uwe
