networkx.linalg.spectrum.laplacian_spectrum¶
-
laplacian_spectrum
(G, weight='weight')[source]¶ Return eigenvalues of the Laplacian of G
Parameters: - G (graph) – A NetworkX graph
- weight (string 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: evals – Eigenvalues
Return type: NumPy array
Notes
For MultiGraph/MultiDiGraph, the edges weights are summed. See to_numpy_matrix for other options.
