latex 使用中的一些问题

一. 关于LaTeX中插入图像时常见的问题

1. visio中画的图转成eps格式：将visio中画的图保存为emf格式，然后在用软件metafile2eps转成eps格式

2. MATLAB中画的图可以直接save as为eps格式

3. LaTeX中应该包含包\usepackage{epstopdf}

 

二. LaTeX直接画图时

1. 画图命令\begin{picture} (x,y)    \end{picture}

 例如：

\setlength{\unitlength}{0.5cm}
\begin{picture} (10,17)
\put(4.5,12) {
\begin{tabular}{| c | c | c | c | c |}
\hline \color{green}{$\bullet$} & \color{green}{$\bullet$} & \color{green}{$\bullet$} & \color{green}{$\bullet$} & \color{green}{$\bullet$} \\
\hline \color{green}{$\bullet$} & \color{blue}{$\bullet$} & \color{blue}{$\bullet$} & \color{blue}{$\bullet$} & \color{green}{$\bullet$} \\
\hline \color{green}{$\bullet$} & \color{blue}{$\bullet$} & \color{red}{$\bullet$} & \color{blue}{$\bullet$} & \color{green}{$\bullet$} \\
\hline \color{green}{$\bullet$} & \color{blue}{$\bullet$} & \color{blue}{$\bullet$} & \color{blue}{$\bullet$} & \color{green}{$\bullet$} \\
\hline \color{green}{$\bullet$} & \color{green}{$\bullet$} & \color{green}{$\bullet$} & \color{green}{$\bullet$} & \color{green}{$\bullet$} \\
\hline
\end{tabular}
}
\put(1,4) {
$
\mathbf{t}(x) = \begin{array}{rl}
\left ( \begin{array}{cc}
& \color{red} {\bullet} \\
sort\uparrow & \left ( \renewcommand{\arraystretch}{0.3}
\begin{array}{c}
\color{blue} {\bullet}\\
\color{blue} {\bullet}\\
\color{blue} {\bullet}\\
\color{blue} {\bullet}
\end{array} \right ) \\
sort\uparrow & \left (
\renewcommand{\arraystretch}{0.3}
\begin{array}{c}
\color{green} {\bullet}\\
\color{green} {\bullet}\\
\color{green} {\bullet}\\
\color{green} {\bullet}
\end{array}
\right )
\end{array}
\right )
& \begin{array}{l}
x_{0,0} \\ \{x_{1,i}\}_i \\ \{x_{2,i}\}_{i}
\end{array}
\end{array}$}
\end{picture}

 

 

PS：今日自己绘图时，始觉绘图之艰辛，小作者为学之严谨精心，倍受鼓舞。
