***** To join INSNA, visit http://www.insna.org ***** Dear SOCNET members, I am working on a weighted network and trying to calculate a matrix, each cell of which will be the sum of the weights of all the possible geodesics between any pair of nodes in the network. Any suggestions on how to calculate such a matrix will be more than valuable.
