Blocking matrices. Transformed versions of the truncated binary matrix, constructed by (a) blocking rows (b) blocking columns (c) superimposing row and column blocking matrices (d) reordering rows and columns to consolidate blocks. Grey shades in effect expresses the degree to which rows conform to column grouping and vice versa. Combining these and optimising the clustering, expresses subnet cores visually as dark areas and overlaps by lighter shades.
