If I do this in that calculator, I can call the function anytime and pass values with no problem. I want to be able to do the same in my HP Prime. Ideas?

You can define functions in the Prime, too. Programs can be called as functions. Just Return the value you want at the end of the program.

Code:

EXPORT MED(Y,Z)
BEGIN
  RETURN [[1+Y*Z/2,Z],[Y*(1+Y*Z/4),1+Y*Z/2]];
END;
