                    y2         1.09091                  -0.36364

Prob:B (ISM, TI, C)

It gives structural composition  for the system:

>>h1=tf(-20);h2=tf(4);h3=tf(30);h4=tf(50);sys=append(h1,h2,h3,h4); 

>>Q=[1 4 2;2 0 0;3 1 2;4 2 3];H=connect(sys,Q,1:2,3:4);

Analytical calculation to determine the transfer matrix.

 Ans:
