Hi Please see the attached patch which makes MATLAB work with org babel eval. Here's the commit message: ob-octave.el: improve MATLAB support * lisp/ob-octave.el (org-babel-octave-evaluate): Improve MATLAB support - Eliminated the code related to MATLAB Emacs Link. This capability was removed from MATLAB release R2009a, 15 years ago. - Fixed the following type of org block evaluation: 1) #+begin_src matlab :results verbatim 2) #+begin_src matlab :results output 3) #+begin_src matlab :results output latex 4) #+begin_src matlab :results file graphics which aid in writing scientific papers. - Minor point, the correct spelling of MATLAB when referencing the product is all upper case. * lisp/ob-matlab.el (header): Update URL for MATLAB * etc/ORG-NEWS (New functions and changes in function arguments): Added entry "ob-octave: improved MATLAB support" Note, I have sent in the paper work for the FSF copyright assignment. Thanks John
