How to retrieve a parameter inside ode solver?
Posted:

Hi:
My question is how to retrieve a parameter value inside ode solver? Let's take the control system as an example. I write my own ODE function. Within the ODE function, I compute the control inputs as u=K*x, where x is the system states and K is a constant matrix. x can be solved by calling ode solver, like ode45. But my question is, how can I get "u"?
I know one solution is that after running the ode solver, then I can write a for loop, like: for i = 1 : length(x) u(i) = K*x(i); end
Is there any way that I can retrieve u without using the for loop after running ode solver?
Thanks.
