up

(Not recommended) Identify parent of object

Using up is not recommended. Use getParent instead.

Syntax

parent = up(object)

Description

parent = up(object) returns the parent of an object in a Stateflow^® chart, State Transition Table, Truth Table, or MATLAB^® Function block.

Examples

Identify Parent of State

Suppose that ch is the Stateflow.Chart object that corresponds to this chart. In this chart, the parent of state A1 is state A. The parent of state A is the chart.

Find the Stateflow.State object named A1.

sA1 = find(ch,"-isa","Stateflow.State",Name="A1");

Identify the parent of state A1. Display the name of the parent.

parent = up(sA1);
parent.Name

ans =

    'A'

Identify the parent of state A. Display the name of the parent.

grandparent = up(parent);
grandparent.Name

ans =

    'Chart'
