When you say "compile", do you mean you use MATLAB Compiler to build an executable?
How are you invoking the code?

Do not use "Save and run" for any function that needs input parameters. Save the routine, yes, but then you need to invoke it from the command line, passing in the parameters you need. For example, at the command line type in
avg([3 5 9 -1 14], 5)
