open_system (Simulink Reference)

Open a Simulink system window or a block dialog box.

Syntax

open_system('sys')
open_system('blk')
open_system('blk', 'force')

Description

open_system('sys') opens the specified system or subsystem window, where 'sys' is the name of a model on the MATLAB path, the fully qualified pathname of a model, or the relative pathname of a subsystem of an already open system (for example, engine/Combustion). On UNIX, the fully qualified pathname of a model can start with a tilde (~), signifying your home directory.

open_system('blk'), where 'blk' is a full block pathname, opens the dialog box associated with the specified block. If the block's OpenFcn callback parameter is defined, the routine is evaluated.

open_system('blk', 'force'), where 'blk' is a full pathname or a masked system, looks under the mask of the specified system. This command is equivalent to using the Look Under Mask menu item.

Example

This command opens the controller system in its default screen location.

```
open_system('controller')
```

This command opens the block dialog box for the Gain block in the controller system.

```
open_system('controller/Gain')
```
