con_nodes Scilab Group Scilab function con_nodes
NAME
con_nodes - set of nodes of a connected component
CALLING SEQUENCE
ns = con_nodes(i,g)
PARAMETERS
i : integer, number of the connected component
g : graph list
ns : row vector, node numbers of the connected component
DESCRIPTION
con_nodes returns the row vector ns of the numbers of the nodes which
belong to the connected component number i. If i is not the number of a
connected component, the empty vector [] is returned.
EXAMPLE
ta=[1 1 2 2 2 3 4 4 5 7 7 9 10 12 12 13 13 14 15];
he=[2 6 3 4 5 1 3 5 1 8 9 8 11 10 11 11 15 13 14];
g=make_graph('foo',1,15,ta,he);
g('node_x')=[197 191 106 194 296 305 305 418 422 432 552 550 549 416 548];
g('node_y')=[76 181 276 278 276 83 174 281 177 86 175 90 290 397 399];
show_graph(g);
con_nodes(2,g)
x_message('Displaying the nodes of component #2');
n=g('node_number');
nodecolor=0*ones(1,n);
nodecolor(1,con_nodes(2,g))=11*ones(con_nodes(2,g));
g('node_color')=nodecolor;
nodediam=20.*ones(1,n);
nodediam(1,con_nodes(2,g))=30*ones(con_nodes(2,g));
g('node_diam')=nodediam;
show_graph(g);
