If a matrix $\mathbf{A}$ is premultiplied by an elementary matrix $\mathbf{E}$, the product EA will be that matrix obtained from A by performing the elementary row operation symbolized by $\mathbf{E}$. Compute the given product for an arbitrary $3 \times 3$ $\operatorname{matrix} \mathbf{A}$. $\left(\begin{array}{lll}0 & 1 & 0 \\ 1 & 0 & 0 \\ 0 & 0 & 1\end{array}\right) \mathbf{A}$
