Line 88: Arithmetic operations like multiplication, inversion, and Cholesky or LR factorization of H<sup>2</sup>-matrices can be implemented based on two fundamental operations: the matrix-vector multiplication with submatrices and the low-rank update of submatrices. While the matrix-vector multiplication is straightforward, implementing efficient low-rank updates with adaptively optimized cluster bases poses a significant challenge.<ref name="HARE14">{{cite journal\|last=Börm\|first=Steffen\|last2=Reimer\|first2=Knut\|date=2015\|title=Efficient arithmetic operations for rank-structured matrices based on hierarchical low-rank updates\|journal=~~Comp.~~Computing ~~Vis.~~and ~~Sci.~~Visualization in Science\|volume=16\|issue=6\|pages=247–258\|arxiv=1402.5056\|doi=10.1007/s00791-015-0233-3}}</ref> == Literature ==
