graph_simp Scilab Group Scilab function graph_simp
NAME
graph_simp - converts a graph to a simple undirected graph
CALLING SEQUENCE
g1 = graph_simp(g)
PARAMETERS
g : graph list of the old graph
g1 : graph list of the new graph
DESCRIPTION
graph_simp returns the simple undirected graph g1 corresponding to
multigraph g. It deletes loops in g, replaces directed edges with
undirected edges and replaces multiple edges with single edges.
EXAMPLE
ta=[1 1 1 2 2 2 3 4 4 4 5 5 6 7 7 8 8 9 9 10 10 10 10 10 11 12 12 13 13 13 14 15 16 16 17 17];
he=[1 2 10 3 5 7 4 2 9 9 4 6 6 8 2 6 9 7 4 7 11 13 13 15 12 11 13 9 10 14 11 16 1 17 14 15];
g=make_graph('foo',1,17,ta,he);
g('node_x')=[283 163 63 98 164 162 273 235 267 384 504 493 409 573 601 627 642];
g('node_y')=[ 59 133 223 311 227 299 221 288 384 141 209 299 398 383 187 121 301];
show_graph(g);
g1=graph_simp(g);
show_graph(g1,'new');
