distSumConnectMatrix: Distance-sum-connectivity matrix

Description

This method calculates the distance-sum-connectivity matrix of a given graph.

Usage

distSumConnectMatrix(g, dist=NULL)

Arguments

a graph as a graphNEL object.

dist

the pre-computed distance matrix of the graph. Will be calculated automatically if NULL.

Value

given graph. This is an adjacency matrix where each edge is weighted according to the reciprocal square root of the product of the adjacent vertices' distance sum.
