[Tex/LaTex] \nearrow and \swarrow together


I'm trying to get an arrow that has an arrow head pointing north east and south west, so like \updownarrow but rotated. I can't seem to find this in LaTeX at all. It has to go inside an equation environment.

Any ideas?

The powerful \ooalign wins; TeX is able to figure out the widths itself.




$a\neswarrow b_{\neswarrow}$

See \subseteq + \circ as a single symbol ("open subset") for more information about \ooalign.
