Returns a table with the edge weights.
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::getEdgeWeights(G) returns a table
with the edge weights of the graph
Graph::getEdgeWeights(G) returns the weight of all edges in
Weights will most probably only be defined, if transportation problems occur.
If FAIL is returned, no weights were defined (this way both, network and graph algorithms handle this situation correct.)
First lets define a graph without edge weights:
G1 := Graph::createCircleGraph(3): Graph::getEdgeWeights(G1)
FAIL was returned, because no edge weights
Graph::getEdges(G1); G1 := Graph::setEdgeWeights(G1, [[1, 2], [3, 1]], [5, 1/2]): Graph::getEdgeWeights(G1)
The first output shows all the edges and the second one the assigned edge weights.
