\end{bmatrix}  =\begin{bmatrix}\partial_x^{-1}-\partial_x^{-1}&\partial_y^{-1}-\partial_y^{-1}&\partial_z^{-1}-\partial_z^{-1}\end{bmatrix}  \end{equation}  Knowing this we require the gradient operator to be a column vector such that when it left operates on the divergence row operator we may create the matrix form above. This gives the form \begin{equation}  \begin{bmatrix} a \\ b \\ c \end{bmatrix}  \begin{bmatrix} \partial_z^{-1}\partial_y^{-1} & \partial_z^{-1}\partial_x^{-1} & \partial_y^{-1}\partial_x^{-1} \end{bmatrix}  =  \begin{bmatrix}  \partial_x^2 & \partial_y\partial_x & \partial_z\partial_x \\  \partial_x\partial_y & \partial_y^2 & \partial_z\partial_y \\  \partial_x\partial_z & \partial_y\partial_z & \partial_z^2  \end{bmatrix}  \end{equation}
