adjacency_spectrum

adjacency_spectrum(G, weight='weight')

Returns eigenvalues of the adjacency matrix of G.

Parameters:

Ggraph

A NetworkX graph

weightstring or None, optional (default=’weight’)

The edge data key used to compute each value in the matrix. If None, then each edge has weight 1.

Returns:
