Let $R$ be a commutative ring with unity.
Let $\mathbf A$ be a square matrix over $R$ of order $n > 0$.
Let $\mathbf I_n$ be the $n \times n$ identity matrix.
Let $R \sqbrk x$ be the polynomial ring in one variable over $R$.
The characteristic matrix of $\mathbf A$ over $R \sqbrk x$ is the square matrix:
- $\mathbf I_n x - \mathbf A$
