hi there, I've used rk4.f90 for backwards integration of a first order Differential equation successfully with a negative step size. My problem now is that I would like to use the odeint.f90 routine to do the same thing. It just doesn't work with x2<x1, I've already tried using negatives h1 and hmin step sizes.
Any Ideas???
Any help is appreciated, thanks
