LaTex入门学习！（Updating）

LaTex作为编辑数学公式，撰写论文是一款极其有利的工具，具体看代码注释：

%：注释开始标志

\\  ：换行

基本格式：

\document[article]

\begin{document}

...

\end{document}

\documentclass{article}
 
\usepackage{amsmath}                % Advanced math typesetting 
\usepackage[utf8]{inputenc }        % Unicode support (Umlauts etc.)
\usepackage{graphicx}               % Add pictures in paper
\usepackage{booktabs}
%\usepackage[ngerman]{babel} % Change hyphenation rules
%\usepackage{listings}              % Source code formatting and highlighting

% main document

\begin{document}         % The document starts here

\title{My first document using \LaTeX{}}
\date{\today{}}
\author{Pheobus}

\maketitle		         % Creates the titlepage	
\pagenumbering{gobble}   % Turns off page numbering
\newpage                 % Starts a new page
\tableofcontents         % Auto-generate a table of content after compile again.
\newpage
\pagenumbering{arabic}   % Turns on page numbering

\section{Basic editing}
Equations without numbering as following:       
\begin{equation*}   % Just exactly one equation
f(x) = f(x-1) + f(x-2)
\end{equation*}     % Ampersand * diminish numbering
Equations with numbering as following:
\begin{align}	
f(0) &= 0\\
f(1) &= 1\\   
f(x) &= f(x-1) + f(x-2)
\end{align}
Align operations as following:
\begin{align*}
f(x) &= x^2\\            % \\ means endline 
g(x) &= \frac{1}{x}\\
F(x) &= \int^b_a\frac{1}{3}x^3dx
\end{align*}

% Line feed means indent in same section.
$f(x) = \sqrt{x}$

\subsection{Matrix}

This is a little bracket matrix:
$
[
\begin{matrix}
1 & 0\\
0 & 1\\
\end{matrix}
]
$
\\
This is a bracket matrix:
% Big brackets to cover matrix:
$
\left[
\begin{matrix}
1 & 0\\
0 & 1\\
\end{matrix}
\right]
$
\\
This is a brace matrix:
$
\left(
\begin{matrix}
1 & 0\\
0 & 1\\
\end{matrix}
\right)
$\\
\section{Section Plus}

\paragraph{Paragraph}
Show a simple equation:
$f(x) = \left(\frac{1}{\sqrt{x}}\right)$\\
Table \ref{tab:table1} shows a simple table.
\begin{table}[h!]
	\centering
	\caption{Caption for the table.}
	\label{tab:table1}
	\begin{tabular}{l|c||r}
	
		1 & 2 & 3\\
		
		\hline
		
		a & b & c\\
		
	\end{tabular}
\end{table}		

\newpage
Table \ref{tab:table2} shows a more sophisticated table.
\begin{table}[h!]
	\centering
	\caption{Caption for table.}
	\label{tab:table2}
	\begin{tabular}{ccc}
		\toprule
		
		Some & actual & content\\
		
		\midrule
		
		prettifies & the & content\\
		
		as & well & as\\
		
		using & the & booktabs package\\
		
		\bottomrule		
	\end{tabular}
\end{table}	


\newpage
Figure \ref{fig:beauty1} shows a beauty.\\
\begin{figure}      % Add a picture.
	\includegraphics[width=\linewidth]{beauty.png}    % Using absolute path while picture to be added not exists in same folder
	\caption{Beauty.}
	\label{fig:beauty1}
\end{figure}

\end{document}
