That distance matrices manage energy between nodes.  The slides show a 5
branch tree to realize 4 nodes (and that distance matrix) and a diagram for
11 degrees of freedom for 6 nodes (3 BSS)  The python code will compute the
branch attenuations based on a supplied distance matrix. There will of
course be some distance matrices that cannot be achieved  per the reduction
of the degrees of freedom required to realize this using
physical devices in a cost effective manner.
