## Homework Statement

The part I'm having problems with is where the last two expressions in 4.13 are equated. Why is x

^{t}Kx*equal to x

^{*^t}Kx*?

## The Attempt at a Solution

x

^{t}Kx* is an inner product and due to symmetry is equal to x

^{*^t}Kx, but wouldnt equating x to x* mean every <x,y> = <x,x> = <y,y>?

Many thanks if someone decides to help me out.
