If you are on Windows, you will need to first figure out how to compile
qhull for Windows.  We haven't done so yet.

If you are on unix, follow the octave-forge/main/geometry/readme 
instructions
for installing qhull.  I haven't tried yet with the most recent qhull 
release.

Download the correct version of octave-forge (octave.sf.net) for your 
particular
version of octave (the latest is for octave 2.1.40 I believe --- if you 
are using
something more recent, you will need to get the CVS version).

    ./configure
    make
    make install

griddata does not work as quickly as I would like.  Talk to the
qhull author about how to improve it if it is not fast enough for
you.
