Simulink.BlockDiagram.expandSubsystem

Replace subsystem with subsystem contents

Syntax

Simulink.BlockDiagram.expandSubsystem(block)

Simulink.BlockDiagram.expandSubsystem(block,'CreateArea',specifier)

Description

Simulink.BlockDiagram.expandSubsystem(block) expands the subsystem block into the system that contains the subsystem. Open or load the model first.

You can expand virtual subsystems that are not masked, linked, or commented. For details, see Subsystems That You Can Expand.

Simulink.BlockDiagram.expandSubsystem(block,'CreateArea',specifier)prevents creating an area around the expanded subsystem.

Input Arguments

block — Subsystem to expand

block path name | block handle

Subsystem to expand, specified as the block path name or block handle.

Example: 'sldemo_enginewc/Combustion'

specifier — Specify whether to create an area

'On' (default) | 'Off'

Option to specify whether to create an area, specified as 'On' to create the area, or 'Off' to not create the area.

Examples

Expand Subsystem

Open the model sldemo_enginewc. Expand the Combustion subsystem.

open_system('sldemo_enginewc')
Simulink.BlockDiagram.expandSubsystem('sldemo_enginewc/Combustion')

The subsystem contents appear in the top level of the model.

Expand Subsystem Without Creating an Area

Expand the Combustion subsystem. The blocks and signals in the Combustion subsystem become part of the system and replace the Subsystem block.

Open the model sldemo_enginewc. Expand the Combustion subsystem but do not create an area.

open_system('sldemo_enginewc')
Simulink.BlockDiagram.expandSubsystem('sldemo_enginewc/Combustion','CreateArea','Off')
