Rank-, Matrices is used. The storage of rank-. matrices as well as operations involving rank-. matrices form the basis of the hierarchical matrix representation and the hierarchical matrix operations, since these are reduced to additions and multiplications by rank-. or small full matrices..In Section 2.1 we recal

Matrix Partitionerty allow for a good approximation by a low-rank matrix block. For the partition of the matrix into (admissible) blocks, we need a block cluster tree. Its construction starts with the cluster tree . introduced in Section 5.3. The practical generation is discussed in Section 5.4. The block cluster t

Definition and Properties of Hierarchical Matrices invariant with respect to transformations by diagonal matrices and transposition. The first essential property of .-matrices is data-sparsity proved in Section 6.3. The storage cost of an n × n matrix is O(. log* .). The precise estimate together with a description of the constants is given in §6.3
