I can't really tell you why 'loadimage' is undefined -- sounds like a
bug with your installation. That being said, 'loadimage' only supports
Octave's own image format (and not ppm), so you won't be able to load
your image this way. You should install the 'image' package from Octave
Forge (http://octave.sf.net) which gives you the 'imread' function that
handles most formats.
