[Tex/LaTex] Aligning a row matrix near a column matrix

matrices

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation} A =  \begin{matrix}\begin{pmatrix}
  A_{00} \\
  A_{01} \\
  A_{10} \\
  A_{11}
\end{pmatrix}\end{matrix} \begin{pmatrix}
  A^*_{00} & A^*_{01} & A^*_{10} & A^*_{11}
\end{pmatrix}
\end{equation}
 \end{document}

I want to align the row matrix near the first row of the column vector. How can I do that?

Best Answer

I would recommend against doing this: your readers will be quite puzzled and probably mistake the row vector as an exponent to the column vector.

\documentclass{article}
\usepackage{amsmath}
\usepackage{delarray} % for the wrong kind of alignment

\begin{document}
\begin{equation}
A = \begin{pmatrix}
  A_{00} \\
  A_{01} \\
  A_{10} \\
  A_{11}
\end{pmatrix}
\begin{pmatrix}
  A^*_{00} & A^*_{01} & A^*_{10} & A^*_{11}
\end{pmatrix}
\end{equation}

\begin{equation}
A =
\begin{gathered}
\begin{array}[t]({@{}c@{}})
  A_{00} \\
  A_{01} \\
  A_{10} \\
  A_{11}
\end{array}
\begin{array}[t]({@{}cccc@{}})
  A^*_{00} & A^*_{01} & A^*_{10} & A^*_{11}
\end{array}
\end{gathered}
\end{equation}

\end{document}

The typesetting in equation (1) is the standard (and non confusing one).
