Newbie Question: Launching Octave Control Systems Toolbox

[Jason Rupert]

I've looked through the GNU Octave manual, and tried simply typing the 
following:
octave-3.2.3:1> DEMOcontrol
error: `DEMOcontrol' undefined near line 1 column 1

I'm working on Mac OS X and installed Octave (octave-3.2.3-i386) on my machine 
from the source forge site via the dmg (http://octave.sourceforge.net/)

What other steps do I need to take in order to be able to launch the Octave 
Control Systems Toolbox (OCST)?  I thought I would simply have to type 
DEMOcontrol as mentioned in the GNU Octave manual, but that did not seem to 
work. 

Thank you for any insights or feedback.
