findlink

Load data for states and links.

load navGraphData.mat

Create state and link tables.

stateTable = table(data.states,data.names,data.numLanes, ...
    VariableNames=["StateVector","Name","Lanes"]);
linkTable = table(data.links,data.linkWt,data.curvature, ...
    VariableNames=["EndStates","Weight","Curvature"]);

Create a navGraph object from the state and link tables.

graphObj = navGraph(stateTable,linkTable);

Create a deep copy of the navGraph object.

graph2 = copy(graphObj)

graph2 = 
  navGraph with properties:

           States: [8×3 table]
            Links: [7×3 table]
    LinkWeightFcn: @nav.algs.distanceEuclidean

Visualize the navGraph object.

show(graphObj)

Find the link IDs of two state pairs. The function returns the link ID for the state pair ["G","A"]. However, it returns 0 as the link ID for the state pair ["C","D"] as the link does not exist in the navGraph object.

linkIDS = findlink(navGraphObj,["G","A"; "C","D"])

linkIDS = 2×1
