곱셈,multiplication의 결과.

여러 가지 product들이 있는데,

수,number의 곱
벡터,vector의 스칼라배 곱 (한 벡터)
내적,inner_product (이하 두 벡터)
외적,outer_product
스칼라곱,scalar_product,dot_product
벡터곱,vector_product,cross_product
삼중곱,triple_product (세 벡터에 대해)

스칼라 삼중곱: A·(B×C)
벡터 삼중곱: A×(B×C)

기타..

합성곱,convolution은 곱의 일종인가?
디리클레_곱 Dirichlet_product

Dirichlet product
합성곱과 같다고.
