function refresh value when variable changes (pass by reference)?

Would it be possible to refresh a function's value?

Say, A =1; B = 1; f = [A B]

Now, if I change A = 3, how should I change f's value without typing f = [A B] again?

It is essentially just like pass by reference, but I thought it is very complicated to do that in Matlab if possible.

This problem occurs because I may want to add variable c to f later, so f = [A B C], and in that way I just need to declare f in the beginning and do not have to change f everywhere.
