I am a huge fan of MATLAB and use it everyday in my professional life. However, one thing that really surprises me is how limited the objects are that can be placed on a MATLAB GUI. There are slider bars, images, buttons, and drop down lists. But what about something like a dial (as in a frequency tuner) or a gauge? Am I missing something that already exists in MATLAB? Or is there a reason why the objects available are so limited?
