摘要
S-strictly dominant B-matrices (SB-matrices) are introduced by Li et al. (Numer Linear Algebra Appl 14:391-405, 2007). In this paper, we give error bounds for the linear complementarity problem when the matrix involved is an SB-matrix, which generalize those of DB-matrix linear complementarity problem and show advantages with respect to the computational cost. Then the perturbation bounds of SB-matrices linear complementarity problems are also provided. The preliminary numerical results show the sharpness of the bounds.
