compute.adjacency.matrix: Computes the adjacency matrix of a multiplex network

In alberto-valdeolivas/RandomWalkRestartMH: Random walk with restart on multiplex and heterogeneous Networks

Description

compute.adjacency.matrix is a function to compute the adjacency matrix of a multiplex network provided as a Multiplex object.

Usage

compute.adjacency.matrix(x,delta = 0.5)

Arguments

x	A Multiplex object describing a multiplex network generated by the function create.multiplex.
delta	A numeric value between 0 and 1. It sets the probability of performing inter-layer versus intra-layer transitions. It is set by default to 0.5. See more details below.

Details

The parameter delta sets the probability to change between layers at the next step. If delta = 0, the particle will always remain in the same layer after a non-restart iteration. On the other hand, if delta = 1, the particle will always change between layers, therefore not following the specific edges of each layer.

Value

A square sparse adjacency matrix created with the Matrix package.
