Description

getTransitiveClosureMat is a support function for inferring a transitive-closure adjacency matrix.

Usage

getTransitiveClosureMat(adjMat)

Arguments

adjMat

is an adjacency matrix of a directed graph of which its elements are binary: zero for no edge, and one for having an edge.

Value

This function returns a transitive-closure adjacency matrix.

Examples

# Given an example of adjacency matrix
A<-matrix(FALSE,5,5)
A[2,1]<-TRUE
A[c(3,4),2]<-TRUE
A[5,3]<-TRUE
# Get a set of reachable nodes of targetNode.

trsClosureMat<-getTransitiveClosureMat(adjMat=A)
