# Equation exceeds one column of IEEE

Equation exceeds one column of IEEE pattern in LaTeX how should I correct it? Please help, the code is attached herewith.

$$\label{eq11} p\left( {v,h|u,y,...} \right) = {\rm{RelU}}\left( {\left[ {\hat b + {w^h}\left\{ {\left( {{v^T}{w^v}} \right) \circ \left( {{y^T}{w^y}} \right)} \right\}} \\ \right]*\left[ {\hat a + {w^v}\left\{ {\left( {{h^T}{w^h}} \right) \circ \left( {{y^T}{w^y}} \right)} \right\}} \right]} \right)$$

Line breaks aren't possible in an equation environment. There are likely several possible ways of doing this, one is to use multline from amsmath, another is a split environment inside equation. Note that \left/\right cannot span a line break, and that you have a lot of brace pairs that are not needed.

\documentclass{IEEEtran}
\usepackage{lipsum}
\usepackage{amsmath}
\DeclareMathOperator{\RelU}{RelU}
\begin{document}
\lipsum*[1]
\begin{multline}\label{eq11}
p(v,h|u,y,...) =
\RelU\bigl( \bigl[ \hat b + w^h \{ ( v^T w^v ) \circ ( y^T w^y ) \}  \bigr]* \\
\bigl[ \hat a + w^v \{ ( h^T w^h ) \circ ( y^T w^y ) \} \bigr] \bigr)
\end{multline}
\lipsum[2]
$$\label{eq12} \begin{split} p(v,h|u,y,...) &= \RelU\bigl( \bigl[ \hat b + w^h \{ ( v^T w^v ) \circ ( y^T w^y ) \} \bigr]* \\ &\phantom{{}=\RelU\bigl(} \bigl[ \hat a + w^v \{ ( h^T w^h ) \circ ( y^T w^y ) \} \bigr] \bigr) \end{split}$$
\lipsum
\end{document}


I suggest using multline. I took the opportunity to improve and simplify the code:

\documentclass{ieeetran}
\usepackage{mathtools}
\usepackage{lipsum}

\begin{document}

\lipsum[1]
\begin{multline}\label{eq11}
p\bigl(v,h\mid u,y\dots \bigr) = \\
\mathrm{RelU}\Bigl( \Bigl[ {\hat b + {w^h}\bigl\{\bigl(v^T w^v \bigr) \circ \bigl(y^T w^y \bigr) \bigr\}}\Bigr] \\ *
\Bigl[ {\hat a + {w^v}\bigl\{ \bigl(h^Tw^h \bigl) \circ \bigl( y^T w^y \bigr) \bigr\}} \Bigr] \Bigr)
\end{multline}

\end{document}
