Hi, thanks for your interest. However, I am sorry... I cannot get your point... Could you please reorganize your question? Thanks.

thanks for your reply, i mean equation (5) should equal equation (7),but i think the inner produce of equation(6) can't deduce the inner produce of equation(7). Can I get the derivation? thanks very much .

⊙ denotes the element-wise product rather than inner product. I successfully derived the equation(7) through equations before.
