Returns a table with the edge costs.
MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.
MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.
Graph::getEdgeCosts(G) returns a table with
the edge costs of the graph
Graph::getEdgeCosts(G) returns the costs of all edges in
Note: Costs will most probably only be defined, if transportation problems occur.
Note: If FAIL is returned, no costs werde defined (this way both, network and graph algorithms handle this situation correct.)
First lets define a graph without edge costs:
G1 := Graph::createCircleGraph(3): Graph::getEdgeCosts(G1)
FAIL was returned, because no edge costs
Graph::getEdges(G1); G1 := Graph::setEdgeCosts(G1, [[1, 2], [3, 1]], [5, 1/2]): Graph::getEdgeCosts(G1)
The first output shows all the edges and the second one the assigned edge costs.
