strong_con_nodes

strong_con_nodes — set of nodes of a strong connected component

Calling sequence

ns = strong_con_nodes(i,g)  

Parameters

i : integer, number of the strong connected component
g : graph list
ns : row vector, node numbers of the strong connected component

Description

strong_con_nodes returns the row vector ns of the numbers of the nodes which belong to the strong connected component number i.
