Re: A Question about adjacency matrix


An adjacency matrix describes relationship between nodes (connection
or no connection). There is often,  but not necessarily a weight
involved. For nodes that are 3D coordinates one could use one of
several distance functions Mathematica has built-in, such as
EuclideanDistance, as  weight. But you can think of many others that
do not involve distance in 3D at all. Any matrix element m[[i,j]]
describes the connection of node i with node j. How you fill it in is
up to you.
