index2state

Find state vectors of state indices

Since R2023a

Syntax

states = index2state(graph,stateIDS)

Description

states = index2state(graph,stateIDS) finds the state vectors states for the queried state indices stateIDS, if they exist in the navGraph object graph.

Examples

Find Successive State Indices and Costs in navGraph Object

Load navGraph data for states and links.

load navGraphData.mat

Visualize the navGraph object.

show(navGraphObj);

Find successive state indices and costs based on a state name.

[succIDS,costs] = successors(navGraphObj,"G")

succIDS = 2×1

     1
     8

costs = 2×1

Find the state vectors of the successive states.

states = index2state(navGraphObj,succIDS)

states = 2×3

    8.0000    7.0000    0.6741

Input Arguments

graph — Graph object

navGraph object

Graph object, specified as a navGraph object.

stateIDS — State indices

column vector of positive integers

State indices, specified as a column vector of positive integers.

Data Types: single | double

Output Arguments

states — State vectors

matrix

State vectors, returned as a matrix in which each row represents a state vector. The state vectors must be of the same size as those in the StateVector column of the States table in the navGraph object graph.

Data Types: double
