That looks like it would work, if you are looping over a1 and N.
That code will not work if a1 or N are vectors.
Note that the definition you gave would also be satisfied by setting all locations to 1, since the definition does not say what should happen at any location where N has any other value.
By the way: how is that definition "making a decision about a1" ? The definition ignores a1.
