how to use Matlab to generate and detect digital I/O from Ni dAQ Is that possible?

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.

thanks.
