[Xy-pic] xymatrix and matrix

[Aleks Kleyn]

Yes, you are right
I want combine diagram of mappings with some notes in one equations. The
code
\[
\begin{matrix}
\xymatrix
{
\overset{\rightarrow}{V}:
D\ar[r]|{*}^{f_{1,2}}&
\overline V\ar[r]|{*}^{f_{2,3}}&
\overset{\circ}{V} 
}
&
\begin{array}{r@{\,}l}
f_{1,2}(d):&\overline v\rightarrow d\ \overline v
\\
f_{2,3}(\overline v):&A\rightarrow A+\overline v
\end{array}
\end{matrix}
\]
>  
creates very good image. However code
\[
\begin{matrix}
\xymatrix
{
D\ar[r]|(.4){*}^{f_{1,2}}&
A\ar[r]|{*}^{f_{2,3}}&
A
\\
&&D\ar[u]|{*}_{f_{1,2}}
}
&
\begin{array}{r@{\,}l}
f_{1,2}(d):&v\rightarrow d\,v
\\
f_{2,3}(v):&w\rightarrow g(v, w)
\\
g&\in\mathcal L(A^2;A)
\end{array}
\end{matrix}
\]
 
has extra line before diagram. The picture looks little shifted. I will
appreciate any idea to improve image.

Please provide your complete preamble, so we can tell
how some of the macros that you use are defined.
