body: <p>I'm having difficulty checking whether all the cell values are zero. I've been looking around and can't find anything to match the array version.</p>
  
  <p>My code:</p>
  
  <pre><code>handles.CheckFinger = cell(1,5);
  handles.CheckFinger = [0 0 0 0 0];
  
  if all(handles.CheckFinger == 0)
      msgbox('No fingers selected for recording.')
  end
