imageSet function not working

I am trying this code http://www.mathworks.com/examples/matlab-computer-vision/725-feature-based-panoramic-image-stitching#7 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 the code directly.

You may have an older version of MATLAB. imageSet was added in R2014b release.

Are you sure you have the Computer Vision System Toolbox? What does

which -all imageSet

say?

[Andrew]

'imageSet' not found.

I didn't realize this is a separate toolbox. Is matchFeatures also in the Computer Vision System Toolbox? It is in the toolbox documentation but I can run it. Do I need to purchase the toolbox to run this example program?

You do need the toolbox. You can get a free trial if you contact the Mathworks.
