I use typeinfo defined in Octave to see what kind of object Octave would consider as output. You can see that [["a',"b"];["c","d"]] is considered as string and not a matrix. And the output in Octave is ans = ab cd See tests below done with character and number. Hope that can help. --8<---------------cut here---------------start------------->8--- * Output typeinfo ** Character #+begin_src octave typeinfo("a") #+end_src #+results: : string #+begin_src octave ["c","d"] #+end_src #+results: : cd #+begin_src octave [["a","b"];["c","d"]] #+end_src #+results: : acbd #+begin_src octave typeinfo([["a","b"];["c","d"]]) #+end_src #+results: : string ** Number #+begin_src octave typeinfo(1) #+end_src #+results: : scalar #+begin_src octave [1,2] #+end_src #+results: : 1.00000000e+000 2.00000000e+000 #+begin_src octave typeinfo([1,2]) #+end_src #+results: : matrix #+begin_src octave ([[1,2];[3,4]]) #+end_src #+results: : 1.00000000e+000 2.00000000e+000 : 3.00000000e+000 4.00000000e+000 #+begin_src octave typeinfo([[1,2];[3,4]]) #+end_src #+results: : matrix --8<---------------cut here---------------end--------------->8--- _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
