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)
