# [Tex/LaTex] Braket notation in LaTeX

braketmath-mode

I am using the braket package to generate bra and ket vectors. However, I could not figure out how to do <0|0> using the package. Is there a command for this?

Use \braket{0|0}:

\documentclass{standalone}

\usepackage{braket}

\begin{document}

$\braket{0|0}$

\end{document}
