[Octave-bug-tracker] [bug #50012] ode23 internal interpolation

[Carlo de Falco]

Follow-up Comment #4, bug #50012 (project octave):

Hi,

Andreas managed to solve the problem on his own during OctConf,
The modified versions of ode23 and runge_kutta_interpolate are in attachment.

It seems the bug was due to the fact that the derivatives used in hermite
interpolation were being given an incorrect value when invoking
runge_kutta_interpolate.

If no one objects I'll turn this files into a changeset and push them
tomorrow.

@Andreas, we also discussed a similar (but not identical) change for ode45, do
you also have a patch for that?

c.

(file #40241, file #40242)
