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)
