Exercise 7.2.3

Answers

Suppose $v = [\begin{matrix} v_{11} & v_{12} & v_{13} \\ v_{21} & v_{22} & v_{23} \\ v_{31} & v_{32} & v_{33} \end{matrix}]$

So the $(1, 1)$ element of $Av$ is $x_{00} v_{11} + x_{- 10} v_{12} + x_{0 - 1} v_{21} + x_{- 1 - 1} v_{22}$

The $(2, 2)$ element of $Av$ is $x_{11} v_{11} + x_{01} v_{12} + x_{- 11} v_{13} + x_{10} v_{21} + x_{00} v_{22} + x_{- 10} v_{23} + x_{1 - 1} v_{31} + x_{0 - 1} v_{32} + x_{- 1 - 1} v_{33}$ .
