The support package for Raspberry Pi converts a Simulink model targeted for Raspberry Pi to a Linux application and saves it on the SD card of the Raspberry Pi board. You can find the d in application in the following folder on your Raspberry Pi:
/home/<user name>/<model name>_rtt/MW/<model name>
For example, if you have a model called "barcode.slx" and your user name is 'pi', Simulink generates the following executable:
You can run this application anytime. Your Raspberry Pi does not have to be connected to your host computer.
You can also auto-start your application on boot by placing the following line of code at the end of /etc/rc.local file:
/home/pi/barcode_rtt/MW/barcode &> /dev/null &
