Obtain the Bode diagram of the following system using MATLAB.

\[\begin{aligned}& \begin{array}{l}\dot{x}_{1} \\\dot{x}_{2}\end{array}=\begin{array}{rrl}0 & 1 \\-30 & 7\end{array} \quad \begin{array}{l}x_{1} \\x_{2}\end{array}+{ }_{30}^{0} u \\& y=\left[\begin{array}{ll}1 & 0\end{array}\right] \begin{array}{l}x_{1} \\x_{2}\end{array}\end{aligned}\]

The input of the system is $u$ and the output is $y$.
