------------------------------------
Hi everyone,
Is there any update on this?
It seems like that there is already quite a lot work done. So I wonder what
needs to be done to get this released?
I am in academia and we start using Java more and more in student projects for
dynamic simulation. The non-stiff solver and the whole package is awesome.
Thank you!

> In version 1.2 several explicit Runge-Kutta methods have been implemented
> which work fine for non-stiff problems. However these methods are not
> suitable for stiff equations. The implementation of an implicit Runge-Kutta
> method such as Radau5 would extend the functionality of the ode package to
> cover the solution of stiff ordinary differential equations.
