G11 = nd2sys([1 1],[1 5 6]);
G12 = nd2sys([1 0],[1 1]);
G21 = nd2sys([1 0 -2],[1 7 12]);
G22 = nd2sys([1 4],[1 3 2]);
G = sbs(abv(G11,G21), abv(G12,G22));
[A,B,C,D] = unpck(G)
this way u can have... use your values

nu={[0 0 .04],[0 -100 -200];[0 .02 .2] [0 0 6]};
de=repmat({[1 12 503/25]},2,2);
sys=ss(tf(nu,de));
Where sys is an object contains all state space represenation matrices, so if you want the A matrix, just type:
sys.A
Enjoy :)
