I will use it as it works clearly clearly well. Following exchange you have with Juan Pechiar related to the way the output is displayed, I would like to submit the following examples : First test : --8<---------------cut here---------------start------------->8--- #+tblname: test | 1 | 2 | 3 | #+source: outtest #+begin_src octave :session *out* :var vec=test :results value vector vecb=[vec]; ans=vecb; #+end_src --8<---------------cut here---------------end--------------->8--- The output is the following : #+results: outtest | 1.00000000e+000 2.00000000e+000 3.00000000e+000 | It is considered as one character and each element are not clearly splitted in table. Certainly handled as string as Juan Pechiar. Second test : --8<---------------cut here---------------start------------->8--- #+tblname: test | 1 | 2 | 3 | #+source: outtestb #+begin_src octave :session *out* :var vec=test :results value vector vecb=[vec;vec]; ans=vecb; #+end_src --8<---------------cut here---------------end--------------->8--- The output is the following : #+results: outtestb | 1.00000000e+000 | 2.00000000e+000 | 3.00000000e+000 | | 1.00000000e+000 | 2.00000000e+000 | 3.00000000e+000 | This time output is splitted in a table as it should be ? _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
