Title:
Mini-lecture course: Introduction into hierarchical matrix technique
Authors:
Litvinenko, Alexander ( 0000-0001-5427-3598 )
Abstract:
The H-matrix format has a log-linear computational cost and storage O(kn log n), where the rank k is a small integer and n is the number of locations (mesh points). The H-matrix technique allows us to work with general class of matrices (not only structured or Toeplits or sparse). H-matrices can keep the H-matrix data format during linear algebra operations (inverse, update, Schur complement).
