Hello,

I'm having a really hard time with Hermitian matrices.

In preparation for my exam next week, I've been trying to figure out this problem:

Given a matrix $\displaystyle A = \left| \begin{matrix} i & 1 & i \\

1 & i & i \end{matrix} \right|$, compute $\displaystyle A^HA$ and $\displaystyle AA^H$.

How do I find $\displaystyle A^H$ given the 2x3 matrix $\displaystyle A$?

Please include all steps. Thank you!
