Roger King 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

Tina Wallace the one hand, this is supported by the use of sparse matrices (cf. §1.3.2.5); on the other hand, one tries to apply fast iterative methods (e.g., the multigrid method , ) whose basic steps are matrix-vector multiplications. Krylov methods are based on the same concept..However, there
