Matlab NIDAQ Native Format

[Mozzi]

Hello,

I recently upgraded to the latest Matlab (R2006) and the latest NI-DAQ drivers.  I used to be able to run the following MATLAB command:

[nativedata, time, start_time] = getdata(AIObject, blocksize, 'native');

And receive "nativedata" in integer format straight off the DAQ.  Now, with the new drivers, "nativedata" returns a 32 bit float which already corrects for the measurement range I specified when initializing the DAQ.  Is this a known problem, and is there any way around it?

Hello Mozzie,

I haven't been able to find much information regarding differences in how data is returned by the getdata command in Matlab.  I might recommend posting this question on the Matlab discussion forums.  Someone there might be able to provide some further insight into this question.
