graph_tool.spectral

This module contains several linear operators based on network structure, which useful for spectral analysis.

Sparse matrices

adjacency	Return the adjacency matrix of the graph.
laplacian	Return the Laplacian (or Bethe Hessian if \(r > 1\)) matrix of the graph.
incidence	Return the incidence matrix of the graph.
transition	Return the transition matrix of the graph.
modularity_matrix	Return the modularity matrix of the graph.
hashimoto	Return the Hashimoto (or non-backtracking) matrix of a graph.
