# [Tex/LaTex] How to organise this matrix in beamer

beamermatrices

I have three vectors that should be in same line in this frame. I can not do it. Could you help me.
The MWE is

\documentclass{beamer}

\begin{document}

%-----------------------------------------------------------------------------------------
\begin{frame}{Identification}
\begin{itemize}
\item  Identification scheme: \citet{Christiano.etal2005}
$Y_{t}=\left[Y_{1t}, MP_{t} , Y_{2t}\right]^{\prime}$

$Y_{1t}= \left[\begin{array}{c} GDP \\ cmp \\ P% \end{array}\right]$; $MP_{t}= \left[\begin{array}{c} i \\ M2% \end{array}\right]$;
$Y_{2t}= \left[\begin{array}{c} RER \\ SP \end{array}\right]$
\item where $Y_{1t}$ represents a subset of variables that...;
\item $MP_{t}$ is the monetary..;
\item $Y_{2t}$ represents a subset...
\end{itemize}

\end{frame}

\end{document}


I want the vector Y1, MP and Y2 in same line, and not as it appear in this image.

Maybe this?? Rather than starting a new equation for each vector, I just separate them with a semicolon and a \quad, within a line of a single equation.

\documentclass{beamer}
\def\citet#1{#1}
\begin{document}

%-----------------------------------------------------------------------------------------
\begin{frame}{Identification}
\begin{itemize}
\item  Identification scheme: \citet{Christiano.etal2005}
$Y_{t}=\left[Y_{1t}, MP_{t} , Y_{2t}\right]^{\prime}$

$Y_{1t}= \left[\begin{array}{c} GDP \\ cmp \\ P% \end{array}\right] ~;\quad MP_{t}= \left[\begin{array}{c} i \\ M2% \end{array}\right] ~;\quad Y_{2t}= \left[\begin{array}{c} RER \\ SP \end{array}\right]$
\item where $Y_{1t}$ represents a subset of variables that...;
\item $MP_{t}$ is the monetary..;
\item $Y_{2t}$ represents a subset...
\end{itemize}

\end{frame}

\end{document}
