Matrix Algorithms using Quadtrees - Indiana University
... Quadtree Matrix Representation. A matrix of order 2p is either homogeneously zero, in which case it is represented NIL; or p = 0 and its element is a non-zero scalar, and is represented by that scalar; or else it is represented by an ordered quaternary tree whose subtrees each represent matrices of ...

Quadtree
A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The regions may be square or rectangular, or may have arbitrary shapes. This data structure was named a quadtree by Raphael Finkel and J.L. Bentley in 1974. A similar partitioning is also known as a Q-tree. All forms of quadtrees share some common features: They decompose space into adaptable cells Each cell (or bucket) has a maximum capacity. When maximum capacity is reached, the bucket splits The tree directory follows the spatial decomposition of the quadtree.
