Checking the below code I observed that tf2ss function is not giving the
expected results for A, B and C, that must be the ones shown on the code.
ss2tf apparently is working well. I did the same code in Matlab and this
software is working as expected. 


 num = [10  10];
 den = [1  6  5  10];
 [A,B,C,D] = tf2ss(num,den)
 %A= [-6  -5 -10;1  0  0;0  1  0];
 %B = [1;0; 0];
 %C = [0  10  10];
 %D = [0];
 %[num,den] = ss2tf(A,B,C,D)
