Description

girth computes the length (number of arcs) of the shortest cycle in an unweighted directed graph g.

Examples

ta=[1 6 2 4 7 5 6 8 4 3 5 1];
he=[2 1 3 6 4 8 8 7 2 7 3 5];
g=make_graph('foo',1,8,ta,he);
g('node_x')=[285  284  335  160  405  189  118  45];
g('node_y')=[266  179   83  176  368  252  64  309];
show_graph(g);
d=girth(g)
