Function File: [a, b, c, d] = tf2ss (num, den)

Conversion from transfer function to state-space. The state space system:

       .
       x = Ax + Bu
       y = Cx + Du
 

is obtained from a transfer function:

                 num(s)
           G(s)=-------
                 den(s)
 

The state space system matrices obtained from this function will be in observable companion form as Wolovich’s Observable Structure Theorem is used.
