.. the following scenario

I have a transfer function in s-space like H(s)=N(s)/D(s).
Using the function tf2ss provides me a transfer function in
state space form commonly written as:

dxdt=A x(t) +B u(t)
y(t)= C x(t) + D u(t)

My question is: How can this be solved using the ode45
solver algorithm by applying u(t) and searching for y(t).

please provide full matlab code as answer
