graph.laplacian: Graph Laplacian

In igraph/rigraph: Network Analysis and Visualization

Graph Laplacian

Description

graph.laplacian() was renamed to laplacian_matrix() to create a more consistent API.

Usage

graph.laplacian(
  graph,
  normalized = FALSE,
  weights = NULL,
  sparse = igraph_opt("sparsematrices")
)

Arguments

graph	The input graph.
normalized	Whether to calculate the normalized Laplacian. See definitions below.
weights	An optional vector giving edge weights for weighted Laplacian matrix. If this is NULL and the graph has an edge attribute called weight, then it will be used automatically. Set this to NA if you want the unweighted Laplacian on a graph that has a weight edge attribute.
sparse	Logical scalar, whether to return the result as a sparse matrix. The Matrix package is required for sparse matrices.
