Summary: In this paper, we consider a class of hierarchically rank structured matrices that includes some of the hierarchical matrices occurring in the literature, such as hierarchically semiseparable (HSS) and certain H2-matrices.
Classification : 65F30, 15A03
Keywords: hierarchically semiseparable (HSS) matrix, H2-matrix, low rank submatrix, tree, QR factorization, unitary-weight representation
