报告摘要:Accurate inverses of structured matrices are desired for application areas of numerical linear algebra. SDD_1 matrices are introduced in Adv. Comput. Math. 35 (2011) 357-373. In this talk, a parametrization of an SDD_1 Z-matrix is investigated. Then the inverses of SDD_1 Z-matrices are computed to high relative accuracy under a weak assumption. Numerical examples are used to illustrate the accuracy of the inverse for the matrices.
