Math & Science ⇒ Bar over Symbol within Brackets

[mjmottram]

Hello,

How can one create a symbol with a bar over it in brackets? As in:

Code: Select all

\bar{\nu}

but with the bar in brackets that are also over the symbol?

By automatic scaling of the delimiters.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}

\begin{document}
  \( \left[\bar{\nu}\right] \)
\end{document}

As suggested in every basic LaTeX documentation.


Best regards and welcome to the board

I may have missed something, but your reply doesn't do what I asked about. I know how to scale the brackets! I want to place the brackets around the bar, not around the entire symbol.

So it seems that the way to do this is:

Code: Select all

\overset{(-)}{\nu}

This isn't the prettiest of solutions though (though looks OK with 1.5 times line spacing). If anyone comes up with anything better I'd like to hear it!

Your original code has been a bit misleading. Try something with the help of the accents package.

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{accents}

\newcommand*{\bbar}[1]{\accentset{[-]}{#1}}
\newcommand*{\pbar}[1]{\accentset{(-)}{#1}}

\begin{document}
  \(
    \bbar{\nu}
  \)

  \(
    \pbar{\nu}
  \)
\end{document}

Just a question for my understanding. Do you now want brackets or parentheses?
