The ode-functions are under development at the moment and do change more quickly 
than in the Debian package that you may have got. Please download the latest 
octave release and then download the latest ode functions from octave-forge, at 
the moment we don't know about which ode23 version you are using ;)

Your example works very well for me (octave 2.9.10, odepkg 2.3.0), if you just 
change the line

 [T,X] = ode23('Logistic',[0:0.01:1000],[x],[],r);

into

 [T,X] = ode23(@Logistic,[0:0.01:1000],[x],[],r);
