FIGURE 11. (a) A binary tree with three levels; see Section 20.4. Each node in the tree owns an index vector I that is a subset of the full index vector I = 1 : n. For the root node, we set I1 = I . Each split in the tree represents a disjoint partition of the corresponding index vectors, so that, for example, I1 = I2 I3 and I7 = I14 I15. (b) A matrix K tessellated according to the tree shown
