Register Customizations with Simulink

In Simulink^®, you can register multiple customizations with an sl_customization function.

Set Up Customization File

To register customizations, use a MATLAB^® function file named sl_customization.m. Place the function on the MATLAB path of the Simulink installation that you want to customize or in the current folder.

You can have more than one sl_customization.m file. The customizations in each file take effect, with conflicts handled by each customization. For example, if you specify priorities for libraries in multiple sl_customization.m files, only one takes effect. If you add the same menu item twice, it appears twice. To ensure that customizations load as expected, refresh the customizations as described in Read and Refresh Customization Files.

The sl_customization function accepts one argument: a handle to the customization manager object (cm). For example:

function sl_customization(cm)

Edit the Customization File

In your sl_customization function, use customization manager object properties and methods specific to your application to register customizations. You can use customization properties and methods to:

Additional MathWorks^® products use the customization manager object and the sl_customization.m file. Refer to the product documentation to learn about the methods and properties that apply to a product other than Simulink.

Read and Refresh Customization Files

The sl_customization.m file is read when Simulink starts. If you change the sl_customization.m file, either restart Simulink or enter this command to see the changes:

sl_refresh_customizations

This command runs all sl_customization.m files on the MATLAB path and in the current folder. Some side effects of running sl_refresh_customizations include:

Rebuilding the Simulink Toolstrip
Rebuilding all Simulink Editor menus
Rebuilding the Library Browser menus and toolbars
Clearing the Library Browser cache and refreshing the Library Browser
Reloading the Viewers and Generators Manager data
