girth(1)                       Scilab function                       girth(1)
NAME
  girth - girth of a directed graph

CALLING SEQUENCE
  d = girth(g)

PARAMETERS

  g : graph list

  d : integer

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

EXAMPLE
  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)
