build_laplacian: Build a Laplacian matrix

In motifcluster: Motif-Based Spectral Clustering of Weighted Directed Networks

Build a Laplacian matrix

Description

Build a Laplacian matrix (combinatorial Laplacian or random-walk Laplacian) from a symmetric (weighted) graph adjacency matrix.

Usage

build_laplacian(adj_mat, type_lap = c("comb", "rw"))

Arguments

adj_mat	Symmetric adjacency matrix from which to build the Laplacian.
type_lap	Type of Laplacian to build. One of "comb" (combinatorial) or "rw" (random-walk).

Value

The specified Laplacian matrix.

Examples

adj_mat <- matrix(c(1:9), nrow = 3)
build_laplacian(adj_mat, "rw")
