Hierarchical matrices

Hierarchical matrices are data-sparse representations of certain densely
populated matrices. They are based on splitting a given matrix into a
hierarchy of rectangular blocks and approximate each of the blocks by a
low-rank matrix. Based on this structure approximative algorithms for
matrix arithmetics can be introduced. For further information and
software, see http://www.hmatrix.org/
