The set of Schur stable matrices is
\begin{align*}
\mathcal S = \{A \in M_n(\mathbb R): \rho(A) < 1\},
\end{align*}
where $\rho(\cdot)$ denotes the spectral radius of a matrix and the set of Hurwitz stable matrices is
\begin{align*}
\mathcal H = \{A \in M_n(\mathbb R): \max_{i} \text{Re}(\lambda...
