title: Undefined function 'imageSet' in matlab
body: <p>I am trying this code <a href="http://www.mathworks.com/examples/matlab-computer-vision/725-feature-based-panoramic-image-stitching#7" rel="nofollow">http://www.mathworks.com/examples/matlab-computer-vision/725-feature-based-panoramic-image-stitching#7</a> but my matlab does not recognize the imageSet function. The error reads "Undefined function 'imageSet' for input arguments of
  type 'char'.". I am not sure what is wrong I copied and pasted directly from the documentation.</p>
