具体操作如下:
1, 新建一个文本文件,输入latex公式,保存为"file1":
代码: 全选
$$\mbox{Power} = \frac{1}{2} \rho A v^3$$
代码: 全选
./latex2eps.sh Wind0 < file1
代码: 全选
dvips: ! DVI file can't be opened.
代码: 全选
echo '\begin{document}' >> $texnew
echo '\thispagestyle{empty}' >> $texnew
谢谢!
附上"latex2eps.sh"的代码:
代码: 全选
#! /bin/sh
#
# latex2eps.sh - translates latex math formula to EPS
#
# Expected usage:
# %filter "latex2eps.sh eqn"
# \begin{displaymath}
# \frac{1}{x+y}
# \end{displaymath}
# %endfilter
# %image "eqn.eps" 250x200
#
# additional style can be used with option -sty, eg.
# latex2eps -sty pslatex -sty color eqn
#
