You should call it as a function. A mex file is a compiled function, similar to a dll or exe. You shouldn't open it through finder because you will not be able to use it that way.

Hi Andrea,
It looks like you are trying to open the MEX file from Finder.
Instead, it should be called as a function while making sure that it is in your MATLAB path. If the file is not in your current search path, you can add it by using the addpath command.
You can find out more information about MEX functions and how they work from the documentation:
If you want to play around with MEX functions, MathWorks also provides example files that you can use as a starting point for making your own MEX functions:
