rk4 was something I wrote long ago to have a simple ODE integrator in
case scipy wasn't installed on my system.  You should be using the
scipy.integrate tools

Thank you very much!!!

I used scipy.integrate tools, splitting complex and real part of the equations, and it worked so good!!

I tried to use: In addition I have filed a ticket for a complex ODE solver.
http://projects.scipy.org/scipy/scipy/ticket/334

But I haven't been able to compile it. It returns a lot of errors when I tried. I suposse that it's because of the fortran compiler, but I don't know.
