如何创建两栏长方程式论文

我有一个很长的公式需要以两列格式输入。我使用的模板是 IEEEtran。这是原始样式的最小文档：

\documentclass[journal,letter]{IEEEtran}

%--------------------- for math formulas-------------------------
\usepackage{mathtools,lipsum,cuted}
\setlength\stripsep{3pt plus 1pt minus 1pt}
%\usepackage{multicol}
\usepackage{amsmath}     
\usepackage{amssymb}                       
\usepackage{mathrsfs}                          
\usepackage{upgreek}
\usepackage{bm}     %bold for Greek symbols
\renewcommand\eqref[1]{(\ref{#1})}
\setlength{\jot}{5pt} 


\begin{document}

    \mathbf{F}(\delta_k) = \begin{bmatrix}
        F(\delta_k) & & & & \\ \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F & & & \\ & \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F & & \\ & & \ddots & \ddots &\\ & & & \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F \end{bmatrix} \medskip
\end{IEEEeqnarray}

我们可以看到这个矩阵太宽了，无法放在一列中。所以我按照论坛上另一篇帖子的指示使用了 \cut 包。

修改后的代码如下：

\documentclass[journal,letter]{IEEEtran}

%--------------------- for math formulas-------------------------
\usepackage{mathtools,lipsum,cuted}
\setlength\stripsep{3pt plus 1pt minus 1pt}
%\usepackage{multicol}
\usepackage{amsmath}     
\usepackage{amssymb}                       
\usepackage{mathrsfs}                          
\usepackage{upgreek}
\usepackage{bm}     %bold for Greek symbols
\renewcommand\eqref[1]{(\ref{#1})}
\setlength{\jot}{5pt} 


\begin{document}
text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before

        F(\delta_k) & & & & \\ \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F & & & \\ & \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F & & \\ & & \ddots & \ddots &\\ & & & \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F \end{bmatrix} \medskip
\end{IEEEeqnarray}
\end{strip}

text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after 

\end{document}

格式如下 在此处输入图片描述

可以看出，公式前的文本将填满所有两列，然后公式才会显示。所以我的问题是，如何让公式前的文本仍然像原始格式一样只填充一列，而公式只占两列？

谢谢。

不用担心，当列中的文本长度超过一列时，会发生什么：

\documentclass[journal,letter]{IEEEtran}
%--------------------- for math formulas-------------------------
\usepackage{mathtools,lipsum}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{mathrsfs}
\usepackage{upgreek}
\usepackage{bm}     %bold for Greek symbols
\renewcommand\eqref[1]{(\ref{#1})}
\setlength{\jot}{5pt}
%--------------------- for wide math formulas --------------------
\usepackage[strict]{changepage}
\usepackage{calc}
    \begin{document}
text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before text-before
\begin{adjustwidth}{0pt}{-\linewidth+\columnsep}
    \begin{IEEEeqnarray}{rCl}
\mathbf{F}(\delta_k) = 
\begin{bmatrix} 
    F(\delta_k) & & & & \\ 
    \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F & & & \\ 
                & \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F & & \\ 
                & & \ddots & \ddots &\\ & & & \Gamma(\delta_k)F_L & F(\delta_k)+\Gamma(\delta_k)F_F 
\end{bmatrix}\medskip
    \end{IEEEeqnarray}
\end{adjustwidth}
text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after text-after
