Dreadfully sorry to be so late to the party but I tried this for the funtion "norm" and it just gave a load of comments. I don't suppose you'd know how to find the "inner workings" of a fuction, would you?

If all you see in the m-file function are comments, then you CANNOT see the "inner workings". The function is a built-in function in the form of compiled code. The MathWorks does not provide the code for compiled functions. Unless of course, you work for them.

The official answer to "How can I see the code for a built-in MATLAB function" is to work at MATLAB as an employee or intern.
The unoffocial answer that I like to give is: If you give Mathworks a $US 10 million non-refundable deposit, then you will get a meeting with someone from Mathworks to discuss getting access to the file you are interested in. (These days it would be an online meeting.)
