There is a vectorial RK implementation in my math packages / programs
URL http://members.xoom.com/gdemont/gsoft.htm
arenstor.adb in:
http://members.xoom.com/gdemont/logiciel/mathprog.zip
uses packages from:
http://members.xoom.com/gdemont/logiciel/mathpaqs.zip
Methods implemented
type t_meth is
(Euler1, Runge_Kutta_class4, Runge_Kutta_3_8_4,
Butcher6, DoPriF7, DoPriF8,
DoPriV8 ); -- V: variable step size (F: fixed)
As you see there is even the Dormand-Prince 13 stages
variable step method...
