I'm not familiar with ob-octave, but I'd imagine ":results vector"
should do the trick. If not then it might be worth adding something
like the following (borrowed from ob-sh.el) to ob-octave.
(org-babel-result-cond (cdr (assoc :result-params params))
results
(let ((tmp-file (org-babel-temp-file "sh-")))
(with-temp-file tmp-file (insert results))
(org-babel-import-elisp-from-file tmp-file)))
Best,
