density_und(CIJ)[source]¶

Density is the fraction of present connections to possible connections.

Parameters:	CIJ (NxN `numpy.ndarray`) – undirected (weighted/binary) connection matrix
Returns:	kden (float) – density N (int) – number of vertices k (int) – number of edges

Notes

Assumes CIJ is undirected and has no self-connections.: Weight information is discarded.
