This cannot be done in MATLAB.
You might be able to get somewhere using the extensions of the (third-party) PsychToolBox

The ability to perceive audio-visual asynchrony is a lot slower ( 100 ms or so) compared to the temporal resolution of the auditory system ( http://www.ncbi.nlm.nih.gov/pubmed/12765396 0.02ms). You can probably come pretty close with standard MATLAB and an audioplayer object (or better its ASIO implementation which I haven't tried yet).
