adjacency_matrix(G[, nodelist, weight]) Return adjacency matrix of G.
incidence_matrix(G[, nodelist, edgelist, ...]) Return incidence matrix of G.

Laplacian Matrix

Laplacian matrix of graphs.

laplacian_matrix(G[, nodelist, weight]) Return the Laplacian matrix of G.
normalized_laplacian_matrix(G[, nodelist, ...]) Return the normalized Laplacian matrix of G.

Spectrum

Eigenvalue spectrum of graphs.

laplacian_spectrum(G[, weight]) Return eigenvalues of the Laplacian of G
