| Jan 13, 2017 at 11:20 | comment | added | Liviu Nicolaescu | You have to be careful about your inner product $(x,y)$. Is it real valued or complex valued? For complex $x$ the quantity $x^TAx$ could be complex. Suppose $n=1$ so $A$ is a real number and $x$ is a complex number. Then $x^TAx= Ax^2$ which is not real for most complex numbers $x$. | |
