How to convert odetovectorfield results to A,B matrices?

Hi.

I would like to know how to convert odetovectorfield results to A,B matrices in a state space model.

The following is the code and the results of that code.

syms y(t) u(t) t;
Dy = diff(y);
D2y = diff(y,2);
D3y = diff(y,3);
DEq = D3y + 6*D2y + 11*Dy + 6*y == 6*u;
[SS,Sbs] = odeToVectorField(DEq)

SS =

Y[2]

Y[3]

6*u(t) - 6*Y[1] - 11*Y[2] - 6*Y[3]

Sbs =

y

Dy

D2y

The A matrix is supposed to be [0 1 0; 0 0 1; -6 -11 -6] and the B matrix is supposed to be B= [0; 0; 6] by the way. Can the matlabFunction of symbolic math toolbox help?

Thanks.
