Using Simulink

Simulink Windows

Simulink uses separate windows to display a block library browser, a block library, a model, and graphical (scope) simulation output. These windows are not MATLAB figure windows and cannot be manipulated using Handle Graphics^® commands.

Simulink windows are sized to accommodate the most common screen resolutions available. If you have a monitor with exceptionally high or low resolution, you might find the window sizes too small or too large. If this is the case, resize the window and save the model to preserve the new window dimensions.

Status Bar

The Windows version of Simulink displays a status bar at the bottom of each model and library window.

When a simulation is running, the status bar displays the status of the simulation, including the current simulation time and the name of the current solver. You can display or hide the status bar by selecting or clearing the Status Bar option on the Simulink View menu.

Zooming Block Diagrams

Simulink allows you to enlarge or shrink the view of the block diagram in the current Simulink window. To zoom a view:

• Select Zoom In from the View menu (or type r) to enlarge the view.
• Select Zoom Out from the View menu (or type v) to shrink the view.
• Select Fit System to View from the View menu (or press the space bar) to fit the diagram to the view.
• Select Normal from the View menu to view the diagram at actual size.

By default, Simulink fits a block diagram to view when you open the diagram either in the model browser's content pane or in a separate window. If you change a diagram's zoom setting, Simulink saves the setting when you close the diagram and restores the setting the next time you open the diagram. If you want to restore the default behavior, choose Fit System to View from the View menu the next time you open the diagram.
