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 \partial_x^2\partial_y\partial_z  \\ b \partial_x\partial_y^2\partial_z  \\ c \partial_x\partial_y\partial_z^2  \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}
