Your function does not actually output anything: your function prints some text to the command window, but printing text using fprintf is a totally different thing to returning an output argument.

How to define MATLAB functions with outputs is a very basic MATLAB concept that is explained in the introductory tutorials (these are highly recommended for all beginners):

How to define MATLAB functions with outputs is also clearly explained in the function help:

Instead of guessing how to use MATLAB, beginners should start to read the MATLAB documentation: the documentation tells us all how to use MATLAB.
