Where E is some exogeneous input and W is a weight matrix derived from the adjancancy matrix A. [HUBBELL, C. H. 1965]
This centrality value is defined by means of a weighted and loop allowed network. The weighted adjacency matrix W of a network G is asymmetric and contains real-valued weights for each edge.
Require connected and loop free network.

HI, thank you for sharing all these good stuffs.
When I calculate Hubbell index for a 176*176 weighted and directed nework, I have a following error message'
"Error in ev > 1 : invalid comparison with complex values". Could you tell me what this means?
Thnak you in advance
