Talk:Matrix element (physics)

Should this article exist?
The matrix element $$ \langle f|H'|i \rangle$$ is called that because it is the $$(f,i)$$ element of the matrix representation of $$H'$$. This is not a different definition from the mathematical matrix element. This page serves no purpose other than confusion, in my opinion. AndreasBM (talk) 10:01, 21 September 2021 (UTC)
