Abstract: The extended vertical linear complementarity problem is a generalization of the linear complementarity problem and has important applications in fields such as engineering, economics, and control theory. By leveraging the upper bounds of the infinity norms of the inverse of S-SDD matrices and SB-matrices, combined with inequality amplification techniques, new estimation formulas for the global error bound of the extended vertical linear complementarity problems of S-SDD matrices and SB-matrices are derived, improving upon existing results. Numerical examples validate the effectiveness of the new estimation formulas.

Key words: extended vertical linear complementarity problem, linear complementarity problem, S-SDD matrix, SB-matrix, error bound
