Data Acquisition Toolbox

The daqhelp Function

You can use the daqhelp function to

• Display command line help for functions and properties
• List all the functions and properties associated with a specific device object

A device object need not exist for you to obtain this information. For example, to display all the functions and properties associated with an analog input object, as well as the constructor M-file help

• daqhelp analoginput
  

To display help for the SampleRate property

• daqhelp SampleRate
  

You can also display help for an existing device object. For example, to display help for the BitsPerSample property for an analog input object associated with a sound card

• ai = analoginput('winsound');
  out = daqhelp(ai,'BitsPerSample');
  

Alternatively, you can display help via the Workspace browser by right-clicking a device object, and selecting Explore -> DAQ Help from the context menu.
