我怎样在投影机中组织这个矩阵？

Question

我有三个向量应该在这个框架中位于同一行。我做不到。你能帮我吗？MWE 是

\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}

我希望向量 Y1、MP 和 Y2 在同一行，而不是像该图像中所显示的那样。

Answer 1

也许是这样?? 我没有为每个向量开始一个新的方程，而是\quad在单个方程的一行内用分号和 , 将它们分开。

\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}
