The matrices in the state-space form of a system model are given.

a. Find the transfer function (or transfer matrix) by using Equation 4.21.

b. Verify the result of (a) by using the ss2tf command.

\(\mathbf{A}=\left[\begin{array}{cc}0 & 1 \\ -2 & -\frac{1}{7}\end{array}\right], \mathbf{B}=\left[\begin{array}{l}0 \\ 2\end{array}\right], \mathbf{C}=\left[\begin{array}{ll}\frac{1}{2} & 1\end{array}\right], \quad D=0\)
