how to use matlab to control the Digital input and outout of ni daq?

I want to do the following with matlab

If detect digital signal iniput from port 0 line 0 (Sensor)
    wait 100ms
    send digital signal output to port 0 line 1 (LED)
    wait 100ms
    send the inverse siganl to port 0 line 1 (turn off LED)

it should runs continuously.

There should be a line of code where I can send/recieve D/I and D/O right? I need that line please.

Thanks
