supra_adjacency: Supra-Adjacency Matrix

In cograph: Analysis and Visualization of Complex Networks

Supra-Adjacency Matrix

Description

Builds the supra-adjacency matrix for multilayer networks. Diagonal blocks = intra-layer, off-diagonal = inter-layer.

Usage

supra_adjacency(
  layers,
  omega = 1,
  coupling = c("diagonal", "full", "custom"),
  interlayer_matrices = NULL
)

supra(
  layers,
  omega = 1,
  coupling = c("diagonal", "full", "custom"),
  interlayer_matrices = NULL
)

Arguments

layers	List of adjacency matrices (same dimensions)
omega	Inter-layer coupling coefficient (scalar or L x L matrix)
coupling	Coupling type: "diagonal", "full", or "custom"
interlayer_matrices	For coupling="custom", list of inter-layer matrices

Value

Supra-adjacency matrix of dimension (NL) x (NL)

Examples

# layers <- list(L1 = mat1, L2 = mat2)
# S <- supra_adjacency(layers, omega = 0.5)
# dim(S)  # (2*n) x (2*n)
