Große
dicht-besetzte Matrizen sind oftmals zu groß um mit Standardalgorithmen
verarbeitet zu werden. Mit Hilfe spezieller Algorithmen, welche die Struktur der
Matrizen ausnutzen, ist dies jedoch möglich. Wir untersuchen Matrizen mit
hierarchischer Rang Struktur (siehe [1]) und mit
Tensor-Train Struktur (siehe [2]). @Article{BenM12, author = {P. Benner and T. Mach}, title = {The Preconditioned Inverse Iteration for Hierarchical Matrices}, year = 2013, journal = {Numer. Lin.
