在编译 tex 文件时我收到一个错误
errorf.tex, line 103, Tex capacity exceeded, sorry [parameter stack size=10000]. \gplbacktext
当尝试编译下一个文件时：
\documentclass[a4paper,12pt,final]{article} % to tamplate
\usepackage{mystyle}
\usepackage{gnuplottex}
\begin{document}
New figure from epslatex terminal:
\begin{figure}
\input{./img/errorf.tex}
\end{figure}
\end{document}
在哪里错误文件 是 Gnuplot 在以下命令的帮助下生成的两个文件之一（另外两个文件是“errorf.eps”）：
set terminal epslatex size 1,1.5 color colortext
set xrange [-3:3]
set yrange [-1:1]
set label 1 at -2, 0.5 "$erf(x) = \\frac{2}{\\sqrt{\\pi}}\\int_0^x\\, dt e^{-t^2}$" centre
set output 'errorf.tex'
plot erf(x)
这是错误文件文件：

答案1
你误用了gnuplottex。请运行pdflatex -shell-escape此示例：
\documentclass[a4paper,12pt,final]{article} % to tamplate
\usepackage{gnuplottex}
\usepackage{amsmath}
\DeclareMathOperator{\erf}{erf}
\begin{document}
In figure~\ref{fig:erf} we see a plot done by \texttt{gnuplot}.
\begin{figure}[htp]
\centering
\begin{gnuplot}
set xrange [-3:3]
set yrange [-1:1]
set label 1 at -1, 0.5 "$\\displaystyle\\erf(x) = \\frac{2}{\\sqrt{\\pi}}\\int_0^x e^{-t^2}\\,dt$" centre
plot erf(x)
\end{gnuplot}
\caption{The $\erf$ function}\label{fig:erf}
\end{figure}
\end{document}
另一方面，在运行示例代码pdflatex之后，运行以下示例，gnuplot
\documentclass[a4paper,12pt,final]{article} % to tamplate
\usepackage{amsmath,xcolor,graphicx}
\DeclareMathOperator{\erf}{erf}
\begin{document}
In figure~\ref{fig:erf} we see a plot done by \texttt{gnuplot}.
\begin{figure}[htp]
\input{errorf.tex}
\caption{The error function}\label{fig:erf}
\end{figure}
\end{document}

显然某些设置是错误的；另一方面，我没有收到任何错误。
答案2
问题已解决。此问题开头指出的错误是由于在 gnuplot 命令中使用了引号。应使用撇号代替引号：
set label 1 at -2, 0.5 '$erf(x) = \\frac{2}{\\sqrt{\\pi}}\\int_0^x\\, dt e^{-t^2}$' centre
第二个问题埃格尔gnuplot 文件中的大小设置不正确导致的结果：
set terminal epslatex size 1,1.5 color colortext
这里应该调整大小以适应 .tex 文件中的图像大小。为了不手动调整大小，可以在插入图像时使用 Tex 中的尺寸自动调整功能：
\resizebox{\linewidth}{!}{\input{./img/errorf.tex}}
