Returns a table with the edge descriptions.
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::getEdgeDescriptions(G) returns a
table with the edge descriptions of the graph
Graph::getEdgeDescriptions(G) returns the
weight of all edges in
Descriptions will most probably only be defined, if transportation problems occur.
If FAIL is returned, no descriptions were defined (this way both, network and graph algorithms handle this situation correct.)
First lets define a graph without edge descriptions:
G1 := Graph::createCircleGraph(3): Graph::getEdgeDescriptions(G1)
FAIL was returned, because no edge descriptions
Graph::getEdges(G1); G1 := Graph::setEdgeDescriptions(G1, [[1, 2], [3, 1]], ["Shortcut", "Highway 66"]): Graph::getEdgeDescriptions(G1)
The first output shows all the edges and the second one the assigned edge descriptions.
