Well, I could be wrong.  In fact, it is likely.  What I did was look at 
the existing code, the MATLAB documentation, the octave sources, and 
what I really need right now.  I said "Bob, what you can do easily 
is.....".  If I was wrong about the classdef stuff, then I will probably 
have to do the same work twice.  On the other hand the first time 
working with somebody else's code, it is likely better to go simple and 
let the chips fall where they may.  Furthermore, if the goal is to be 
MATLAB compatible (and it is a serious goal for me), then both are 
necessary.

I expect you could do the whole thing in 15 minutes.  If you prefer, I 
can just dump what I am trying to do and you can do it or just tell me 
how.  It is probably worth my time and yours for me to poke around and 
learn the sources and then have you critique my solutions.  Slow and a 
bit painful, but that is the only way I know of to learn the code and it 
gets it off of your shoulders.  I am just now getting to the point where 
I am modifying sources, and will probably have questions and I hope you 
don't mind.  Of course I will document it when I am done. 

Octave is quite complex.  I hope you appreciate the astonishing code 
base you have built.  I sure do.
