Latex写作实现伪代码

Latex-算法伪代码 - 严二姨的文章 - 知乎
https://zhuanlan.zhihu.com/p/266241159

写作开头导入相应的包：

\usepackage{algorithm}
\usepackage{algorithmicx}
\usepackage{algpseudocode}  % 如果不想在算法伪代码模块中显示 end for 和 end while，则使用  %\usepackage[noend]{algpseudocode}

对应伪代码部分进行写作：

\begin{algorithm}
	%\textsl{}\setstretch{1.8}
	\renewcommand{\algorithmicrequire}{\textbf{Input:}} %将require转化为Input
	\renewcommand{\algorithmicensure}{\textbf{Output:}} %将ensure转化为Output
	\caption{STVMD based on STFT}
	\label{alg1}
	\begin{algorithmic}[1]
		\STATE Initialization:$\left\{ {s_{k,t}^1} \right\},\left\{ {\omega _{k,t}^1} \right\},\lambda _t^1,n \leftarrow 0$
		\STATE  ${s_{r,t}}\left( \omega  \right) = \int_0^{ + \infty } {
   
   {s_r}\left( \tau  \right){w_h}\left( {t - \tau } \right)} \exp \left( {j\omega \tau } \right)d\tau $   (via STFT)
		\REPEAT
		\STATE $n \leftarrow n + 1$
		\STATE Update $ s_{k,t}^{n + 1} $ based on Equation~(\ref{eqn_8})
		\STATE Update $\omega _{k,t}^{n + 1}$ based on Equation~(\ref{eqn_9})
		\STATE Update $\lambda _t^{n + 1} $ based on Equation~(\ref{eqn_10})
		\UNTIL $\sum\limits_{k=1}^P  {
   
   {

					{\vphantom {
   
   {\left\| {s_{k,t}^{n + 1}\left( \omega  \right) - s_{k,t}^n\left( \omega  \right)} \right\|_2^2} {\left\| {s_{k,t}^n\left( \omega  \right)} \right\|_2^2}}} \right.

		\STATE   Update ${s_k}\left( t \right)$ based on Equation~(\ref{eqn_11_12})  (via ISTFT)
		\ENSURE  decomposed modes $ \left\{ {
