You can create it yourself, for instance with TikZ/PGF.  It provides
good support for arrows.

   http://www.ctan.org/tex-archive/graphics/pgf/base/doc/generic/pgf/version-for-pdftex/en/pgfmanual.pdf

Another possibility is to use the arrow from a font (the same you are
using when indicating a function) inside a LaTeX picture environment.
The second arrow must be rotated.  This is supported by LaTeX's
graphics package.  But some manual tweaking is required.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
