Hello! I want to make a simulation using the function rk (Runke Kutta method) from the package "dynamics" in the following form: rk([x2,1-x1-0.2*x2],[x1,x2],[0,0],[t,0,50,0.1])$ I need to pass state events to rk, for example limitations like "if x>5 then 5 else x" Is that possible? If yes, how can that be done? Thanks Wilhelm Haager
