Description

Update the graph by removing one vertex

Usage

graphUpdateOne(w, G, vec01)

Arguments

w

a numeric vector of vertex weights

G

a matrix of transition weights

vec01

a binary vector indicating the set of vertices planned to be removed: the vertex corresponding to the first zero in this vector will be removed
