Here's part of a solution using pstricks:

Jay

\documentclass[12pt]{article}

\usepackage{mathtools}
\usepackage{pst-node}
\psset{linewidth=0.6pt}
\psset{nodesepA=-10pt}
\psset{nodesepB=-15pt}

\begin{document}
$\begin{pmatrix} \Rnode{A}{a} & \Rnode{B}{b} & \Rnode{C}{c}\\ d & e & f \\ \Rnode{G}{g} & \Rnode{H}{h} & \Rnode{I}{i} \end{pmatrix} \begin{matrix} \Rnode{AA}{a} & \Rnode{BB}{b} \\ d & e \\ \Rnode{GG}{g} & \Rnode{HH}{h} \end{matrix} \ncLine{->}{A}{I} \ncLine{->}{B}{GG} \ncline{->}{C}{HH} \ncLine{->}{BB}{I} \ncLine{->}{AA}{H} \ncLine{->}{C}{G}$
\end{document}
