Re: ode23

It's from the standard Octave package. I didn't install odepkg. Should I be using it instead? That would be a little bit uncool in terms of the better, upgraded standard Octave

Hi,

I cannot reproduce your issue, your example works for me with no error ...

Are you using ode23 form odepkg or the built-in implementation?
What do you see if you type "pkg list, which ode23"?
