Digilent adverises that USB-3114 is Matlab compliant. Does not work with Matlab

The MatLab DAQ Toolbox supports the USB-3114, but only asynchronous operations.  Please try the following code:

d = daqlist("mcc")
dq = daq("mcc")
addoutput(dq, "Board0", "Ao0", "Voltage")
for i=0:10
delete (dq);

The single-channel update rate is approximately 100 S/s and is system-dependent. For additional assistance, please contact Mathworks, the authors of the MCC support.

Thank you for the response.  I will try this routine. Is the 10 ms update time (100 S/s) time due to the Matlab limitation or MCC?  Why the 1 second pause?

OK, Thank you for the information. This does work.  I see the nomenclature is buried as a Matlab daq help topic "Getting started with MCC devices".  I didn't see any mention of that Matlab resource in any of the manuals. 

Is there a way to suppress the the Matlab warning "Added channel does not support clocked sampling:...." ?

100 Hz is sufficient for my purposes now.  Is there a higher rate DAC available with similar current output capabilities?  Can you recommend an output current buffer with no drifts or offsets?
