我必须写一个如下图所示的流程图
我已经使用了这些包，
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
但我无法得到我想要的。我希望这里的一些 LaTeX 专家可以帮助我。
另一个选项是使用algorithm2e包，是否可以同时拥有这两个代码？
当我使用半命令时，它会转到其他页面？如何在一页中编写完整的流程图？
\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{matrix,shapes,arrows,positioning,chains}
\begin{document}
% Define block styles

diamond,

rounded corners
},

例如：

\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{matrix,shapes,arrows,positioning,chains}
\begin{document}
% Define block styles

draw,
text width=10em,
text centered,
rounded corners
},
cloud/.style={
draw,
ellipse,
minimum height=2em
},
descr/.style={
fill=white,
inner sep=2.5pt
},
connector/.style={
-latex,
font=\scriptsize
},
rectangle connector/.style={
connector,
to path={(\tikztostart) -- ++(#1,0pt) \tikztonodes |- (\tikztotarget) },
pos=0.5
},
rectangle connector/.default=-2cm,
straight connector/.style={
connector,
to path=--(\tikztotarget) \tikztonodes
}
}
\begin{tikzpicture}
\matrix (m)[matrix of nodes, column sep=2cm,row sep=8mm, align=center, nodes={rectangle,draw, anchor=center} ]{
