After check out source code of `ob-octave.el`, I found only one places
used `ans.m`:
```
(defvar org-babel-octave-wrapper-method
"%s
if ischar(ans), fid = fopen('%s', 'w'); fprintf(fid, '%%s\\n', ans);
fclose(fid);
else, dlmwrite('%s', ans, '\\t')
end")
```
Might Octave package versions compatition issue or something elseraised
this error. Based on the error hints, should be the calling to `ans` is
wrong. After tesing upper code in Octave REPL, it works fine. that
weird. The upper variable is just a wrapper around src block `body`for
saving`ans` to file.
Anyway, hope somebody who knows elisp and Octave can check this out.
