MATLAB: How to specify a message for the Simulink model that could appear when I execute the help command in MATLAB

simulink

How do I specify a message for my model (MyModel.SLX) that could appear when I execute the following command?

>> help MyModelName

Best Answer

To create a model description that can be queried using the "help" keyword, please go to the Description tab in Model Properties and enter the description. You could also do this programmatically by using the "set_param" command in the following way:

>> set_param(gcs, 'Description', 'This is a sample model description')

MATLAB: How to switch between child subsystems of a Variant Subsystem through a pop-up menu or a radio button

Right-click on the Variant Subsystem, select 'Block Parameters (Subsystem)', and enable 'Override variant conditions and use the following variant'.

Then, please refer to the following steps:

1. Create a mask for the Variant Subsystem (Right click on the Variant Subsystem > Mask > Create Mask...)

2. In the Parameters & Dialog tag, add a Popup (or a Radio button) control, specify a desired prompt message, as well as the name of the variable you will use to switch between variants (e.g., myVar)

3. In the Property editor, in the 'Properties' section, click on 'Type options' and enter the desired options (the options should correspond to the Variant Control names). Then select an initial variant for the field 'Value'.

    The variant control names can be found by right-clicking on the Variant Subsystem > Block Parameters (Subsystem), in the 'Variant Control' column.

4. In the Property editor, in the 'Dialog' section, add the following Callback:

>> set_param(gcb,'OverrideUsingVariant',get_param(gcb,'myVar'));

If you wish to activate variants programmatically from MATLAB rather than Simulink canvas from the subsystem mask, please execute the following command:

>> set_param(subsystemName,'OverrideUsingVariant',variantControlName);

For further details, please refer to the attached Simulink model (R2018a).

MATLAB: How to modify the model callback functions programmatically

You may use the "set_param" function.

Here is the example code about how to change the 'InitFcn' programmatically using one of our shipped example 'vdp.slx':

>> vdp
>> set_param('vdp','InitFcn','a = 2;')

>> vdp
>> set_param(gcs,'InitFcn','a = 2;')

Please reference our documentation page for more details about the 'set_param' function and Model Callbacks:
