Start the Simulink Software

To build models, use the Simulink® Editor and the Library Browser.

Start the MATLAB Software

Before you start Simulink, start MATLAB®. See Startup and Shutdown.

Configure MATLAB to Start Simulink

The first model that you open in a MATLAB session takes longer to open than subsequent models because, by default, MATLAB starts Simulink when opening the first model. This just-in-time starting of Simulink reduces MATLAB startup time and avoids unnecessary system memory use.

To speed up opening the first model, you can configure MATLAB startup to also start Simulink. To start Simulink without opening models or the Library Browser, use start_simulink.

Depending on how you start MATLAB, use the command:

  • In the MATLAB startup.m file

  • At the operating system command line, with the matlab command and the -r switch

For example, to start Simulink when MATLAB starts on a computer running the Microsoft® Windows® operating system, create a desktop shortcut with this target:

matlabroot\bin\win32\matlab.exe -r start_simulink

On Macintosh and Linux® computers, use this command to start Simulink when you start MATLAB:

matlab -r start_simulink

Open the Simulink Editor

To open the Simulink Editor, you can:

  • Create a model. On the MATLAB Home tab, click Simulink and choose a model template.

    Alternatively, if you already have the Library Browser open, click the New Model button . For additional ways to create a model, see Create a Model.

  • Open an existing model. To open recent models, on the MATLAB Home tab, click Simulink.

    Alternatively, if you know the name of the model you want, at the MATLAB command prompt, enter the name, such as vdp. For additional ways to open a model, see Open a Model.

    Tip   The Simulink Editor opens on top of the MATLAB desktop. To move the MATLAB desktop on top, in the Simulink Editor, select View > MATLAB Desktop.

Open the Library Browser

Use any of these techniques to open the Simulink Library Browser from MATLAB:

  • On the Home tab, click Simulink, and choose a model template. In the new model, click the Library Browser button .

  • At the command prompt, enter slLibraryBrowser.

The Library Browser opens and displays a tree view of the Simulink block libraries on your system. As you click libraries in the tree, the contents of the library appear in the right pane.

    Note:   Simulink comes with block libraries in addition to the Simulink library. These libraries support simulating supplied example models that contain blocks from those libraries. However, you can generate code or modify these blocks only with the relevant product licenses.
