I just need a hint at least A^* is A conjugated and trasposed.Can you please define y*?
Also do you expect someone here to show you the proof? If yes, then please read the guidelines for this forum. Thanks!
Mu is conjugated. ex. 1+i conjugated is 1-i.what is the significance of \(\displaystyle \bar{\mu}\) vs. just \(\displaystyle \mu\) ?
