How should my matrix (multiplication) equation look like?

Consider the following matrix: \begin{align} X=\begin{bmatrix} x_{11}\;\; x_{12} \\ x_{21}\;\; x_{22} \\ \end{bmatrix} \end{align} I want to multiply each element by $e_{ij}$, so I finally have the following matrix: \begin{align} EX=\begin{bmatrix} e_{11}x_{11}\;\; e_{12}x_{12} \\ e_{21}x_{21}\;\; e_{22}x_{22} \\ \end{bmatrix} \end{align} But what should I multiply $X$ with to obtain $EX$?
