Name
predecessors — tail nodes of incoming arcs of a node
Calling Sequence
a = predecessors(i,g)
Description
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.nodes.graphics.x=[285 284 335 160 405 189 118 45];
g.nodes.graphics.y=[266 179 83 176 368 252 64 309];
g.nodes.graphics.colors(2,8)=color('red');
show_graph(g);
a=predecessors(8,g)
hilite_nodes(a);
