how to include my own matlab functions in simulink

Am using 2013A. Am new to Simulink. I want to include Matlab functions I've already written. Simulink lets me create a user-defined Matlab function block (User-defined functions, Matlab function fcn()

which does create a new blank function that I can edit. But what I want to do is open my existing matlab stuff and use it as a simulink object. The only thing I can think of is to copy and paste my matlab function into the blank template for the fcn() object created by Simulink but this is unbelievably klugey. Any ideas??

Use Interpreted Matlab Function

I tried this - just opens up a block where I can call a matlab function (sin is the default). So then I can put my own function name there? That's OK except this restricts me to only returning a single value. Is this something I just have to accept?

No, you can return what you want, and choose your own function
