This matrix will become the covarient form of the electromagnetic tensor $F_{\mu\nu}$. However this is 6 equations for 8 unknowns, leaving two free parameters that could take any value in the input four-vectors $\textbf{r}_1,\textbf{r}_2$.
But this shows that \begin{equation}
\textbf{E}={_t\textbf{r}_1} \times {_t\textbf{r}_2} \\
\end{equation}
That is the electric field corresponds to the corss product of the spatial comonents of the four vectors.
