rich_club_bd
(CIJ, klevel=None)[source]¶ The rich club coefficient, R, at level k is the fraction of edges that connect nodes of degree k or higher out of the maximum number of edges that such nodes might share.
Parameters: - CIJ (NxN
numpy.ndarray
) – binary directed connection matrix - klevel (int | None) – sets the maximum level at which the rich club coefficient will be calculated. If None (default), the maximum level is set to the maximum degree of the adjacency matrix
Returns: - R (Kx1
numpy.ndarray
) – vector of rich-club coefficients for levels 1 to klevel - Nk (int) – number of nodes with degree > k
- Ek (int) – number of edges remaining in subgraph with degree > k
- CIJ (NxN
