Simulink blocks available for RPi in MATLAB2013a.
Simulink 2013a version has extended target support for RPi model B. ow you can develop applications for raspberry pi on Simulink by using the Simulink blocks for RPi. A new firmware for RPi, compatible with Simulink is Raspbian Wheezy, which can be downloaded by using the "target updater" of simulink. This firmware (OS image) should be flashed to a SD card and then be used to boot the RPi. Then connect RPi to a router or directly to host PC by using ethernet cable. Simulink uses TCP/IP protocol to download simulink models and run the same on RPi. For more information, visit this page. You will have to note down the IP address of RPi by executing the command "ifconfig" on RPi's terminal and use the same as reference to link the host PC and RPi. In case you need more help, please leave a comment or mail me.
