The function RGB2YCBCR is part of Image Processing Toolbox.

Have you looked at the documentation. It's referring Poynton, C. A.A Technical Introduction to Digital Video. The same reference as in this Wikipedia article.

If you have the toolbox you can also look at the code how the function is implemented with edit rgb2ycbcr (if it does not use mex).
