In normal equation I do not have any problem. However for long equation I need to use figure so that my equation appear more obviously. (Note: I am using two column paper style).
This is the equation style that I use:
\documentclass[journal]{IEEEtran}
\usepackage{cite}
\usepackage{graphicx}
\usepackage{refstyle}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{lipsum}
\begin{document}
\title{\huge Single line equation in two column paper}
\maketitle
\section{First} \label{first}
\lipsum[1-6]
\begin{figure*}[t]
\normalsize
\begin{align} \label{eqn1}
Long_{eqn}^{1} &= aaa aaa aaa aaa + aaa aaa aaa aaa aaa aaa aaa aaa + aaa aaa aaa aaa aaa aaa + aaa aaa aaa aaa \nonumber\\
&+ bbb bbb bbb bbb bbb bbb + bbb bbb bbb bbb bbb bbb bbb bbb bbb +bbb bbb bbb bbb bbb bbb bbb bbb +bbb bbb bbb bbb bbb \nonumber\\
&+ ccc ccc ccc ccc ccc ccc +ccc ccc ccc ccc ccc ccc ccc ccc+ ccc ccc ccc ccc ccc ccc + ccc ccc ccc ccc ccc ccc ccc ccc .
\end{align}
\end{figure*}
\lipsum[2-5]
\section{Second} \label{second}
\lipsum[3-8]
\begin{figure*}[t]
\normalsize
\begin{align} \label{eqn2}
Long_{eqn}^{2} &= aaa aaa aaa aaa + aaa aaa aaa aaa aaa aaa aaa aaa + aaa aaa aaa aaa aaa aaa + aaa aaa aaa aaa \nonumber\\
&+ bbb bbb bbb bbb bbb bbb + bbb bbb bbb bbb bbb bbb bbb bbb bbb +bbb bbb bbb bbb bbb bbb bbb bbb +bbb bbb bbb bbb bbb \nonumber\\
&+ ccc ccc ccc ccc ccc ccc +ccc ccc ccc ccc ccc ccc ccc ccc+ ccc ccc ccc ccc ccc ccc + ccc ccc ccc ccc ccc ccc ccc ccc .
\end{align}
\end{figure*}
\lipsum[4-8]
\end{document}
My problem is that; I can't put this equation in its actual position. It will be either on the top or bottom of the next page. I want it to be in its normal position.
I have checked previous related questions, such as (How to influence the position of float environments like figure and table in LaTeX?) and (How to use the placement options [t], [h] with figures?), but non of them was useful to my case. Therefore, I preferred to ask this question.
Best Answer
I think a better solution would be to use the
cuted
package from thesttools
bundle. It is dedicated to insert some material full-width in a twocolumn environment:
