 Exactly what do you mean by argmax?
If you want a simple vector norm, v / Sqrt[v.v], where v is the vector you want to normalize, should do the trick.

I want to slove this problem but X(k) and Y(k) are different
dimension vectors.

k = argmax | X(k) - Y(k) |

I thought of simply doing argmax |X(k)| - |Y(k)| but that will give
me a different result...

thanks in advance,
David.
