odeiv: Runge-Kutta 9(8)

[Jerome BENOIT]

Hello,

I am wondering if there is any interest for incorporating
the Runge-Kutta 9(8) [1] into GSL to somehow complete
the current odeiv stepper collection:
as I may implement it to integrate numericaly SDE
(not ODE), it will cost to me tiny efforts to bring it to GSL.
I will be very glad to do so.

Reference:

Thanks,
Jerome
