Probably the best solution is something similar to David's suggestion of:

  function in = inoctave ()
    persistent inout = exist("OCTAVE_VERSION","builtin") != 0;
    in = inout;
  endfunction

but that won't work in Matlab, so you'll need to write it as

  function retval = inoctave ()
    persistent inout;
    if (isempty (inout))
      inout = exist ('OCTAVE_VERSION', 'builtin') ~= 0;
    end
    retval = inout;
  end


If this isn't in the FAQ, it should be.
