Auxiliary function. Computes combinatorial matrix.

Combinatorial matrix computed according to soft configuration model or 'regular' gnp model.

ComputeXi(adj, directed, selfloops, regular = FALSE)

Arguments

adj	adjacency matrix
directed	boolean, whether the model is for a directed network
selfloops	boolean, whether the model contains selfloops
regular	boolean. Is the combinatorial matrix computed for configuration model or for regular gnp model? default FALSE.

Value

combinatorial matrix

Examples

data('adj_karate')
xi = ComputeXi(adj_karate, directed = FALSE, selfloops = FALSE)
