You could define your own.  It would be

  function val = matlabroot ()
    val = OCTAVE_HOME;
  endfunction

That's precisely what will appear in Octave 3.1.

I haven't looked at the original file for all the context, but this
seems wrong since Octave also runs on Windows systems.

Also, you probably want to install in a subdirectory of the site
directory rather than in the 2.9.12 directory, and it would probably
be best not to hardcode a version number...  You can get the site
directory with

  octave_config_info ("localfcnfiledir")

If this should be version- or api-specific, you should use
"localapifcnfiledir" or "localverfcnfiledir".
