Non ordinary differential equation



Hello,

I'm struggling with a non ordinary differential equation analogous to a
diffusion equation:

'diff(f,t) = -K * 'diff(f,x) + r * (1 - f/f0) * f^2 ;

where K, r and f0 are constants.

I'm not hopping to find an explicit solution but I'd like to be able to plot
it numerically. Is there any method similar to Runge-Kutta for non-ordinary
differential equations ?

Thank you.
