centrality_laplacian: Laplacian Centrality

In cograph: Analysis and Visualization of Complex Networks

Laplacian Centrality

Description

Energy drop from the graph Laplacian when a node is removed (Qi et al. 2012). Measures a node's importance to the overall network energy.

Usage

centrality_laplacian(x, ...)

Arguments

x	Network input (matrix, igraph, network, cograph_network, tna object).
...	Additional arguments passed to centrality (e.g., weighted, directed).

Value

Named numeric vector of Laplacian centrality values.

See Also

centrality for computing multiple measures at once.

Examples

adj <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), 3, 3)
rownames(adj) <- colnames(adj) <- c("A", "B", "C")
centrality_laplacian(adj)
