Since you linked to the help document about sets I assume you found the basic functions for union, intersection, etc. Since cells can contain a variety of different things, I'm not sure how to provide you any more information about the list of cells you put in your email. Also, I am fairly certain that does basic set functions do not operate on cells, only two dimensional arrays. You may be able to use cellfun with those functions to do what you want, but I'm not certain it will work.

Maybe if you provide a better idea of what type of data you're working with, and what mathematical functions you really want to perform on them, we can provide some better feedback.
