How to detect and send digital I/O using matlab?

How to use matlab to detect and generate digital input output form a NiDAQ using matlab?
I do not want to use simulink. Is that even possible? I have a sensor and a LED light. When I put my figure near the sensor the LED turn on, when I let go the LED will go off. IS that even possible in Matlab? I believe matlab don't run things continuously.

Jay Feldman said once you have configured the object as sending digital I/O then you just use the regular commands to send data to the port; there is no specific "send digital I/O" command.
