Graph Laplacian

Source: R/structural-properties.R
graph.laplacian.Rd

[Deprecated]

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

Deprecated, use normalization instead.

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.
