I know how to set initial conditions of a state space model when using the state-space block in Simulink. However, how is it done using the "ss" command?

e.g. given A, B, C and D, how can I set the initial condition x0 using the "ss" command?

G = ss(A,B,C,D,x0) % not the correct code but just to give an idea of what I am trying to achieve

The "lsim" command does change the initial condition but I just want to set the initial condition without simulating the system.

Thanks for your time in advance.

I'm almost certain that the initial conditions are not a settable (is that a word?) property of ss objects. The initial conditions have to be provided to functions that use them.
