尝试使用.tikz从 MATLAB 脚本生成的文件时，该.tex文件出现错误并且无法构建。
代码.tex如下：
\documentclass{article}
\usepackage{amsmath}
\numberwithin{figure}{section}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\newlength\figureheight
\newlength\figurewidth
\begin{document}
\begin{figure}[h]
\setlength\figureheight{2cm}
\setlength\figurewidth{0.84\textwidth}
\input{IntroGraph.tikz}
\end{figure}
\end{document}
IntroGraph.tikz 如下所示：
\definecolor{mycolor1}{rgb}{0.00000,0.44700,0.74100}
