- For the computation of the generalized singular value decomposition (GSVD) of a large matrix pair (A, B) of full column rank, the GSVD is commonly formulated as two mathematically equivalent generalized eigenvalue problems, so that a generalized eigensolver can be applied to one of them and the desired GSVD components are then recovered from the computed generalized eigenpairs.Author: Jinzhi Huang, Zhongxiao JiaPublish Year: 2019Cite as: arXiv:1907.10392 [math.NA]Comments: 25 pages, 5 figuresMSC classes: 65F15, 65F35, 15A12, 15A18, 15A42arxiv.org/abs/1907.10392
