LAST ONE FOR TODAY! :-)

	I'm running Octave 1.0 under
	Linux 0.99.15 #1 Thu Feb 3 19:55:32 CST 1994
	from Slackware 1.1.2 on my 486DX33.

(In my ongoing quest to get the MATLAB controls toolbox to run under
Octave)

Using an empty matrix as an index apparently isn't allowed in octave,
but perhaps it should be (especially for compatability with MATLAB).
This error causes problems with parallel.m and ssdelete.m.
