Every if must have a matching end statement. This is always required.

It is not always required that every function has a matching end statement. It is required for functions inside of scripts, and if you use nested functions. However if you have a .m file that starts with function and you do not have nested functions then you can omit the end statement matching every function statement. You cannot mix and match in one file: either do not use any end matching function or else every function must have a matching end. You cannot have some with matching and others without.
