Details:

According to the documentation, there are 4 built-in OutputFcns available.


odeplot  Plot all components of the solution vs. time
odephas2         2-D phase plane plot of the first two solution components
odephas3         3-D phase plane plot of the first three solution components
odeprint         Print solution and time step


Octave currently only supports 'odeplot'.  At a minimum, 'odeprint' looks like
it would be simple to implement.

The other two should probably be implemented only *after* odeplot has been
optimized.  odeplot is currently quite slow because it calls plot for every
single cycle, rather than just updating the existing data.
