networkx.linalg.spectrum.laplacian_spectrum¶
-
laplacian_spectrum
(G, weight='weight')[source]¶ Returns 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_array for other options.
