Examples
Show Callback Tracing for Double Mass-Spring System
Callbacks are commands you can define that execute in response to a specific modeling action, for example, opening a model or stopping a simulation. When you enable Show Callback Tracing in Simulink Preferences, the MATLAB Command Window displays callbacks as they are invoked. For more information on callbacks, see Customize Model Behavior with Callbacks.
Display the callback that runs when you open the Double Spring Mass System model. The example model represents a double spring-mass-damper system with a periodically varying forcing function.
Open Simulink Preferences. In the Simulink Toolstrip of any open model window, on the Modeling tab, in the Evaluate and Manage section, select Environment > Simulink Preferences.
In Simulink Preferences, on the General Pane, select Show Callback Tracing.
Click Apply.
If the Double Spring Mass System model is open, close it.
Open the Double Spring Mass System model.
openExample('simulink_general/sldemo_dblcart1Example')
Evaluating callback 'PostLoadFcn' for sldemo_dblcart1 Callback: crtanim2([],[],[],0,1);
The invoked callback is a
PostLoadFcn
callback that runs thecrtanim2
function.You can use the information about the type of callback to find where the commands that it executes are specified. To do so for this example, right-click the canvas and select Model Properties.
On the Callbacks tab, select PostLoadFcn*. The right pane of the Model Properties dialog box shows the callback that ran when the model opened.
Turn Off Display of Variable Values in Block Parameters Dialog Box
By default, when you specify a block parameter as a variable, the text box in the Block Parameters dialog box where you specify the parameter displays the value of the variable. You can use the display to obtain the value that a variable has at a certain point during simulation, and to debug your model.
You can use Simulink Preferences to turn the display off, for example when you are demonstrating a model and the value of the variable is confidential, or when the display gives away the answer to a problem that your students or trainees are supposed to solve.
In this example, view and then turn off the display of the heater air temperature in
the Thermal Model of a House model. The heater air temperature is
specified as the variable THeater
in the Heater
subsystem.
To open the model, use this command.
openExample('simulink_general/sldemo_househeatExample')
To open the
Heater
subsystem, double-click the Subsystem block.To see the value of the
THeater
variable, double-click theHeater Air Temperature
block. The Block Parameters dialog box opens.The Constant value text box displays the name of the variable on the left and the value of the variable on the right.
Close the Block Parameters dialog box.
Open Simulink Preferences. In the Simulink Toolstrip, on the Modeling tab, in the Evaluate and Manage section, select Environment > Simulink Preferences.
In Simulink Preferences, on the Editor Pane, turn off Display value of parameter when specified using variables.
Click Apply.
In the model, double-click the
Heater Air Temperature
block. The Block Parameters dialog box opens. The Constant value text box no longer displays a value.

For each model listed, you can select any of the options in this table.
Option | Result |
---|---|
Restore | Overwrite the original model file with the autosave copy and delete the
autosave copy. The software will close the model and reload from the restored
file. If you select Keep a copy of original model file, you
can save copies of the original model files named
or
. |
Delete Autosave | Delete the autosave copy. |
Ignore | Leave the model and the autosave copy untouched. This setting is the default. The next time you open the model, the Model Recovery dialog will reappear and you can choose to restore or delete autosave files. |
Alternatively, click the Restore All, Delete All, or Ignore All button to select that option for all listed models.
Closing a modified model deletes any autosave copy.
The software might not autosave a model for these reasons:
Autosave does not occur for models that are part of the MATLAB installation, so you do not create autosave copies of those models.
Autosave does not occur if the autosave file or location is read-only.
Autosave does not occur in the Parallel Computing Toolbox™ software.
If a segmentation violation occurred, then the last autosave file for the model reflects the state of the autosave data prior to the segmentation violation. Because Simulink models might be corrupted by a segmentation violation, the software does not autosave a model after a segmentation violation occurs.
