Connected components of a graph

Description

The getComponents function returns all the connected components of a graph.

Usage

1
getComponents(nodes, arcs)

Arguments

nodes

vector containing the nodes of the graph, identified by a number that goes from 1 to the order of the graph.

arcs

matrix with the list of arcs of the graph. Each row represents one arc. The first two columns contain the two endpoints of each arc and the third column contains their weights.

Value

getComponents returns a list with all the components and the nodes of each one ($components) and a matrix with all the arcs of the graph and its component ($components.arcs).

# Components
getComponents(nodes, arcs)
