Array of the minimum $\dfrac{f}{\partial f}$ over the lattices that surround each matter object

Description

Estimate typical length scales, one per each matter object, by computing $\dfrac{f}{\partial f}$, where $f$ is a field given as input, and $\partial$ represent a derivative of it. Presently, the derivatives are computed separately along each spatial dimension, as 1D derivatives.
