Hermitian Matrix

567 Views Asked by At

Can you show that the range space and the null space of a Hermitian matrix are mutually orthogonal. I was reading a conference paper and they used it too easily I suppose. Can you please prove.

Let $H$ be a Hermitian matrix. Let $u$ be a vector such that $Hu=0$, and $v$ be any vector.

$$\left<u,Hv\right>=\left<H^*u,v\right>=\left<Hu,v\right>=\left<0,v\right>=0$$
