National Instruments DAQMX function support in matlab

Hi,

I have a national instruments PCI-DIO-32HS digital card and I'm trying to use matlab's data acquisition toolbox. I have Daqmx 9.8 installed, matlab can see the card and communicate with it fine. My issue is that I cannot find any support in Matlab's legacy or session based acquisition that supports what NI calls burst export clock (<http://zone.ni.com/reference/en-XX/help/371893D-01/6536and6537help/programming_burst/)>. This functions exports the clock from the card to a device, the ni function supports arguments for clock polarity used to trigger an event (e.g. off when high). Although matlab has an addclockconnection, there seems to be no support for an of these additional arguments (see link above).

Am I missing something here?
