Computes the distances between pairs of points taken from two different three-dimensional point patterns.

Logical. Specifies whether to apply a periodic edge correction.
Given two point patterns in three-dimensional space, this function computes the Euclidean distance from each point in the first pattern to each point in the second pattern, and returns a matrix containing these distances.
This is a method for the generic function

This function expects two

Y are identical and are rectangular,
then the distances will be computed in the ‘periodic’
sense (also known as ‘torus’ distance): opposite edges of the
rectangle are regarded as equivalent.
This is meaningless if the window is not a rectangle.
