You can use string replacement within LaTeX (xstring and collcell packages). For the blocks, I use dashed lines from arydshln (: in header and hdashline in rows).
documentclassarticle
usepackagearray,arydshln
usepackagexstring,collcell
newcommandToDot[1]StrSubstitute#10cdot
begindocument
beginequation
W = left(
beginarray *3>collectcellToDotc<endcollectcell :
*3>collectcellToDotc<endcollectcell :
*3>collectcellToDotc<endcollectcell
1 & 0 & 0 & 0 & -1 & 0 & 0 & 0 & -1 \
0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \
0 & 0 & 1 & 0 & 0 & 0 & 0 & 0 & 0 \hdashline
0 & 0 & 0 & 1 & 0 & 0 & 0 & 0 & 0 \
-1 & 0 & 0 & 0 & 1 & 0 & 0 & 0 & -1 \
0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \ hdashline
0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \
0 & 0 & 0 & 0 & 0 & 0 & 0 & 1 & 0 \
-1 & 0 & 0 & 0 & -1 & 0 & 0 & 0 & 1 \
endarray
right)
endequation
