It’s part of the Image Processing Toolbox, and has been around for at least a decade. If you have the Toolbox installed, you should have all the functions in your posted code.

You may have a corrupted path.

Run these from your Command Window or a script:

restoredefaultpath 
rehash toolboxcache 

Then try again. (You may have to close and restart MATLAB after this as well.)

If that fails to correct the problem, use the Contact Us link in the top right corner of this page, and request Tech Support. (Run the ver command first, since you will need that output.)
