Hi all,

How can I find the angle between two complex vectors? for example

$\displaystyle \begin{bmatrix}-0.8187 + 0.0000i \\-0.1488 - 0.0089i \\ -0.0266 + 0.0167i \\ 0.5010 + 0.2166i \\ -0.0886 + 0.0264i \end{bmatrix}

\begin{bmatrix}-0.1510 + 0.0000i \\-0.0257 + 0.0195i \\ 0.5214 + 0.1720i \\ -0.8147 + 0.0624i \\ 0.0827 + 0.0185i \end{bmatrix}$

Thanks
