module procedure estimate_lengthscale_field module function estimate_lengthscale_field(this, get_field, n_mat) result(scales)

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