Diagonal double arrow

[Yannis Krontiris]

Hi!

I want to use a diagonal double arrow (like \nearrow but double direction)
in my latex document, but AMS symbols don't seem to have that. Are there any
suggestions? I thought I should overlap \nearrow and \swarrow, but I don't
know how to do that. I hope there is an easier way!...

Thanks
Yannis

\begin{document}
$\nearrow$ and $\swarrow$ and $\neswarrow$ and $\longneswarrow$
\end{document}

Have you checked the Symbol List (see sig)? If there is no
double NE arrow listed you could rotate one of the other arrows

\usepackage{graphicx}
\rotatebox[origin=c]{45}{$\leftrightarrow$}

Perhaps

\makebox[0pt][l]{$\nearrow$}$\swarrow$

(I seem to remember that there is a simpler macro to set height
and width of a symbol/character/box to zero - anyone?).

The Comprehensive LaTeX Symbol List shows how to overlap \nearrow and
\swarrow in the "Where can I find the symbol for...?" section.
