You can get that error if you do not have the Computer Vision Toolbox licensed.
What shows up for
which vision.PointTracker
(You can also get that error if you are using MATLAB R2010a through R2011b, as vision.PointTracker was introduced in R2012a.)

Hi thank you for your response,
I had uninstalled the toolbox and tried to reinstall the tool box but keep getting this error Downloads/MathWorks/R2017a/archives/common/vision_common_1487291449.enc (No such file or directory) Would you like to retry installing vision_common? If you press No, the installer will exit without completing the installation. More information can be found at /var/folders/2_/mrz3s5yj6kg1gdfv9prz0k580000gn/T/mathworks_Sunaina.log
Hi
yes it says that it was not found, even though i had downloaded it properly?
