Andrew, I see that there are your functions, so it's great that you
are interested in contributing them to the Octave community.  Since it
is your code, you can certainly do that.  But I would like to remind
others here of the obnoxious clause in

  http://www.mathworks.com/matlabcentral/disclaimer.html

that says

  All content contained in the MATLAB Central File Exchange may only
  be used with MathWorks products.

Even though the file exchange requires you to submit your code under
the terms of a BSD-style license, they are claiming this additional
restriction on it.  So I think we should be careful to obtain
permission from original authors if we would like to use code from the
file exchange with Octave.
