I would like to make all arrows that should be parallel in my commutative diagram, actually parallel. Here is my diagram:
\begin{center}
\begin{tikzpicture}
\matrix (m) [matrix of math nodes,row sep=3em,column sep=4em,minimum width=3em]
{
F(\mu F) & FA \\
\mu F & A \\};
\path[-stealth]
(m-1-1) edge node [left] {$ in_{F} $} (m-2-1)
edge node [above] {$F(h)$} (m-1-2)
(m-2-1.east) edge node [above] {$h$}
node [above] {} (m-2-2)
(m-1-2) edge node [right] {$ g $} (m-2-2)
;
\end{tikzpicture}
\end{center}
How can I shift this away and get a proper square?
