Is
it true that for a QM operator in its matrix form must be in the
same basis that the state its acting on for the matrix
multiplication to make sense. For example for me to multiply the
matrix form of the Hamiltonian of the system with an eigenfunction
of the hamiltonian should all the matrix elements for the
hamiltonian operator be made using the eigenbasis of the
hamiltonian. If so then please provide a proof. If this isnt the
case can you offer a simple example.
