[pstricks] 2 pictures (psmatrix) side by side

[Richard Sudarmono]

Hallo!
I would like to make 2 psmatrix pictures side by side.
Can anybody tell me, how can I make it or where to find the answer?
Except with minipage environtment, is there another method?

Thanks in advance.

Newbie in pstricks world,

\begin{pspicture}(5,5)\psgrid
  \pnode(1,4){Pin1}
  \pnode(4,4){Pin2}
  \ncLine{Pin1}{Pin2}
  \mput{\Large $\Rightarrow$}
\end{pspicture}
