Transmitting a signal from matlab

Greetings, I am trying to send a signal from my matlab program to a microcontroller (I am thinking of using parallax educational propeller). I am beginner and I have no idea how to start or if I should generate a voltage or something from matlab and send it to the micro controller.

Any help is greatly appreciated Thank You

There are several external interfacing options depending on whether you would like to connect to a hardware (say serial) port directly, or call into existing C++ libraries, COM components, etc (ie. drivers).
