I see.  I have used MATLAB heavily for many years, and many of my
suggestions and programs are now incorporated into MATLAB
(including lcm, normcdf, norminv, erfcinv, readpnm, writepnm,
readras, writeras), so I like to think I am fairly knowledgable.

However, I don't know how Octave is supposed to work, when the
docs don't explicitly say, so I'm not sure what is a mere
_difference_ between MATLAB and Octave and what is a _bug_.
Perhaps I'll just point out the differences I find and leave it up
to you to decide if this really is a bug.
