\begin{equation}  \nabla\mathbf{F}^T \to \begin{bmatrix}\nabla = \begin{bmatrix}  \partial_x^2\partial_y\partial_zF_x & \partial_x^2\partial_y\partial_zF_y & \partial_x^2\partial_y\partial_zF_z\\   \partial_x\partial_y^2\partial_zF_x & \partial_x\partial_y^2\partial_zF_y & \partial_x\partial_y^2\partial_zF_z \\   \partial_x\partial_y\partial_z^2F_x & \partial_x\partial_y\partial_z^2F_y & \partial_x\partial_y\partial_z^2F_z   \end{bmatrix}  Like a metric?  \end{equation}
