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 : NumPy array
Eigenvalues

Notes
For MultiGraph/MultiDiGraph, the edges weights are summed. See to_numpy_matrix for other options.
