What error message do you see? Which version of MATLAB do you have installed? Do you have the Computer Vision toolbox licensed and installed?

You need to store all of that code into a file named MotionBasedMultiObjectTrackingExample.m . MATLAB does not permit defining functions at the command prompt.
