predecessors returns the row vector of the numbers of the tail nodes of the incoming arcs to node i for a 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);
a=predecessors(8,g)
show_nodes(a);
