Given two vectors of size $n$
$$u = [u_1, u_2, u_3, …, u_n ] $$
and
$$v = [v_1, v_2, v_3, …, v_n ] $$
What is the name of the operation "$u ? v$" such that the result is a vector of size $n$ of the form
$$u ? v = [v_1 \times u_1, v_2 \times u_2, v_3\times u_3, …, v_n \times u_n ]$$
For want of a better name, I have termed it "piecewise vector multiplication".
What is this operation normally known as in the literature?

It's pointwise product. See Wikipedia articles here and here
