Text Formatting ⇒ Operator: vector representation in a particular frame

[pc0019]

Hi,

I'm not sure if I'm looking for a symbol, or some way to format an existing symbol (probably \longrightarrow).

At the moment I have:

Using the following latex, LaTeX respectively:

Code: Select all

\vec{e}_0
	\begin{array}{c}
		\longrightarrow \\ O
	\end{array}
	(1,0,0,0)

\vec{e}_0 \overrightarrow{O} (1,0,0,0)

But I would like:

Please ignore all details aside from the placement of the arrow and the 'O'. I can't seem to get them right! Any help would be greatly appreciated.

Many thanks,
Patch

Hi Patch,

you could use \xrightarrow of amsmath:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
  \vec{e}_0 \xrightarrow[\mathcal{O}]{} (1,0,0,0)
\]
\end{document}

Stefan, thank you for your quick response - and for cleaning up my original post! This is exactly what I wanted.
