state2index
Description
Examples
Find Indices of States in navGraph
Object
Load navGraph
data for states and links.
load navGraphData.mat
Create a table to use to search for the state ID.
stateData = table([3 6 0.142170047601527; 1 1 1],["F"; "A"],[2; 2], ... VariableNames={'StateVector','Name','Lanes'});
Find the indices of the states.
id = findstate(navGraphObj,stateData)
id = 2×1
6
0
The navGraph
states table contains a state corresponding to the first state data, so the function returns its index. However, the states table does not contain a state that corresponds to the second state, so the function returns 0
.

Input Arguments
graph
— Graph object
navGraph
object
Graph object, specified as a navGraph
object.
Output Arguments
stateIDS
— State indices
column vector of positive integers
State indices, returned as a column vector of positive integers. When the function
does not find a specified state vector, the value for the corresponding element in
stateIDS
is 0
