This is a notation question. Assume one is given two vector a and b, and one constructs a third vector c whose elements are given by

ck=akbk

Is there any standard notation for this simple operation?

Is the notation below acceptable?

c=a⊗b

**Answer**

(Minor edits.)

It turns out that the symbol ⊙ is often used to denote component-wise multiplication (a few examples are given in the comments below); ∘ and ∗ are common alternatives.
