How do I stop a simulation in Simulink from the MATLAB command window?

Best Answer

You can use the following command at the MATLAB command prompt to stop a simulation in SIMULINK from the MATLAB command window:

set_param(gcs, 'SimulationCommand', 'stop')

For more information on what other simulatin commands you can use with SET_PARAM see the Using Simulink Guide here:

MATLAB: How to access simulation information with the command SIM in Simulink 7.3 (R2009a)

The ability to obtain information about the current simulation when using SIM is not available in Simulink 7.3 (R2009a).

This is because the SIM command blocks the MATLAB command window and other commands cannot be executed until the SIM command has completed execution. The advantage is that you can use this for MATLAB-script automation of data processing.

To work around this issue you can use the SET_PARAM command to start/stop your simulation:

set_param(<modelname>,'SimulationCommand','start')

More information can be found at:

 <http://www.mathworks.com/access/helpdesk/help/toolbox/simulink/slref/f23-7515.html>

This does not block the MATLAB command window and you can retrieve all the needed information of the current simulation.

MATLAB-file automation: Here you need to check the state of the simulation because the command line is not blocked.

MATLAB: How to run the Real-Time Windows Target simulation from the command line or a MATLAB file

You can use the SET_PARAM function to connect and simulate your target model from the MATLAB command line or a MATLAB file. See the following example for the steps necessary to simulate your model:

1. First, you need to change the simulation mode of a model from 'normal' to 'external'. You can do this with the following command:

set_param('model_name','SimulationMode','external')

2. Second, you need to connect to the target. You can do this with the following command:

set_param('model_name','SimulationCommand','connect');

3. Now, you need to run the code:

set_param('model_name','SimulationCommand','start');

4. To stop the real time code:

set_param('model_name','SimulationCommand','stop');

5. And finally, to disconnect from the target:

set_param('model_name','SimulationCommand','disconnect');
