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?



Is there an existing name for "piecewise vector multiplication"
It's pointwise product. See Wikipedia articles [here](http://en.wikipedia.org/wiki/Matrix_multiplication#Hadamard_product%20%22here%22) and [here](http://en.wikipedia.org/wiki/Pointwise_product)
