Hello,
To configure the excitation for the 4472 you can use the AI Parameter.vi. The parameter name is DSA onboard excitation. When using the excitation make sure to enable AC coupling by using the AI Config.vi. One thing to note is that the 4472's input range is +/- 10 Volts. I am not sure on how to configure this in Matlab. You could create a dll in LabVIEW and then call the dll in Matlab. Have a good one.
