Calculate Graph Laplacian Matrix
Description
Compute unnormalized, normalized, or random-walk Laplacian from an adjacency matrix.
Usage
cal_laplacian(W, type = c("unnormalized", "normalized", "randomwalk"))
Arguments
W
A square adjacency matrix (can be dense or sparse).
type
Type of Laplacian to compute: "unnormalized", "normalized", or "randomwalk".
Value
Laplacian matrix of the same class as input.
Examples
W <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), nrow = 3)
cal_laplacian(W, type = "normalized")
