function for use in graphs that are used with the psfrag package in LaTeX
Description
tex is a little function to save typing when including TeX
commands in graphs that are used with the psfrag package in LaTeX to
typeset any LaTeX text inside a postscript graphic. tex
surrounds the input character string with \tex[options]{}.
This is especially useful for getting Greek letters and math symbols
in postscript graphs. By default tex returns a string with
psfrag commands specifying that the string be centered, not
rotated, and not specially enlarged or shrunk.
Usage
tex(string, lref='c', psref='c', scale=1, srt=0)
Arguments
string
a character string to be processed by psfrag in LaTeX.
lref
LaTeX reference point for string. See the psfrag
documentation referenced below. Default is "c" for centered
(this is also the default for psref).
