This is a wiki supplement to the official GNU Octave Manual at http://www.octave.org/doc/interpreter. Its structure shall largely mirror that, and may even heavily borrow from it. Our aim of course, is to contribute back the users' contribution here into the main manual. As you write into these pages, please try your best to mirror the structure of the official manual above.
