Hi There

I am trying to do the fast fourier transform of a discrete array from a solution of a non-linear ordinary differential equation. Or in other words I want to solve a non-linear ODE and then take some discrete measurements of that ODE. Then using this I want to plot the discrete fourier transform of this discrete data. Does anyone know how to do that? I have particular difficulty in getting the discrete measurements of the ODE.

Thanks so much for your help
