Is it possible to use \IEEEeqnarray in beamer?

Question

I have a report written in IEEEtran class. Now I need to make slides in beamer. There are lot of equations formatted according to \IEEEeqnarray with different alignments, so it will be cumbersome to transform them all to either \align or \eqnarray environments which are possible environments in beamer.

I am curious if there is any way to use \IEEEeqnarray environment in beamer class? I did try \usepackage{IEEEtrantools}, but its not working in following example code:

\documentclass{beamer}
\mode<presentation> {   
    \usetheme{Warsaw} 
    \useoutertheme{infolines} } 
\usepackage{graphicx} % Allows including images 
\usepackage{booktabs} % Allows the use of \toprule, \midrule and \bottomrule in tables 
\usepackage{epstopdf} 
\usepackage[font=small,skip=0pt]{caption} 
\usepackage[backend=bibtex]{biblatex} \bibliography{references} 
\usepackage{bibentry} 
\usepackage{mathtools}
%\usepackage{IEEEtrantools} 
\beamertemplatenavigationsymbolsempty  
\usepackage[framemethod=tikz]{mdframed} %for slide transition %---------------------------------------------------------------------------------------- %  TITLE PAGE %----------------------------------------------------------------------------------------
\title[\date{\today} ]{Heading} % The short title 
\author{kaka} % Your name \institute[my univ] % Your institution as it will appear on the bottom of every slide, may be shorthand to save space { My University \\ % Your institution for the title page \medskip \textit{[email protected]} % Your email address } \date{\today} % Date, can be changed to a custom date

\begin{document}    
    \begin{frame}  
        \frametitle{Overlapping Composite Binary Hypotheses}   
        Due to the uncertainty in the noise variance, composite binary hypotheses ....... 
        \begin{IEEEeqnarray*}{rCl} 
            SNR&=&\dfrac{E[|\vec{a}^ {\ \dagger} \vec{b}s|^2]}{E[|\vec{a}^\dagger \vec{w}|^2]} \\ 
            &=& \frac{E[|s|^2]\cdot |\vec{a}^\dagger \vec{b}|^2}{E[|\vec{a}^\dagger \vec{w}|^2]} 
        \end{IEEEeqnarray*}             
    \end{frame} 
\end{document}

Answer 1

You are already using IEEEtrantools, hence it is possible to use IEEEeqnarray. The following works:

\documentclass{beamer}


\mode<presentation> {

\usetheme{Warsaw}
\useoutertheme{infolines} }
\usepackage{graphicx} % Allows including images
\usepackage{mathtools} %
\usepackage{IEEEtrantools}   %% makes IEEE tools available in other classes.
\beamertemplatenavigationsymbolsempty
\begin{document}

 \begin{frame}  \frametitle{Overlapping Composite Binary Hypotheses}   Due to the uncertainty in the noise variance, composite binary hypotheses ....... 
\begin{IEEEeqnarray*}{rCl} 
SNR&=&\dfrac{E[|\vec{a}^ {\ \dagger} \vec{b}s|^2]}{E[|\vec{a}^\dagger \vec{w}|^2]} \\ 
&=& \frac{E[|s|^2]\cdot |\vec{a}^\dagger \vec{b}|^2}{E[|\vec{a}^\dagger \vec{w}|^2]} 
\end{IEEEeqnarray*}

  \end{frame}
\end{document}

However, as you are also loading mathtools, the job done by IEEEeqnarray can be easily done by align*

\documentclass{beamer}


\mode<presentation> {

\usetheme{Warsaw}
\useoutertheme{infolines} }
\usepackage{graphicx} % Allows including images
\usepackage{mathtools} %
\beamertemplatenavigationsymbolsempty
\begin{document}

 \begin{frame}  \frametitle{Overlapping Composite Binary Hypotheses}   Due to the uncertainty in the noise variance, composite binary hypotheses .......
\begin{align*}
SNR&=\dfrac{E[|\vec{a}^ {\ \dagger} \vec{b}s|^2]}{E[|\vec{a}^\dagger \vec{w}|^2]} \\
&= \frac{E[|s|^2]\cdot |\vec{a}^\dagger \vec{b}|^2}{E[|\vec{a}^\dagger \vec{w}|^2]} \end{align*}

  \end{frame}
\end{document}

As suggested by LaRiFaRi, you may want to add the option retainorigcmds to IEEEtrantools, if you want to use only IEEEeqnarray*.
