Hi, I that [itex]<I|M|J>=M_{I}^{J}[/itex] is just a way to define the elements of a matrix. But what is [itex]|I>M_{I}^{J}<J|=M[/itex] ? I don't know how to calculate that because the normal multiplication for matrices don't seem to work. I'm reading a book where I think this is used to get a coordinate representation of a group with a matrix representation as:
[itex]\hat{G_{i}}=q^{I}(G_{i})_{I}^{J}p_{j}[/itex] where q and p are the coordinates and the conjugate momenta.
Can someone give me an easy example? :)
