A new error bound for the linear complementarity problem when the matrix involved is a -matrix is presented, which improves the corresponding result in (Li in Electron. J. Linear Algebra 31(1):476-484, 2016). In addition some sufficient conditions such that the new bound is sharper than that in (García-Esnaola and Peña in Appl. Math. Lett. 22(7):1071-1075, 2009) are provided.
给出了当所涉及矩阵为(a -)矩阵时线性互补问题的一个新的误差界，它改进了（Li于2016年发表在《电子线性代数杂志》31(1):476 - 484）中的相应结果。此外，还提供了一些充分条件，使得新的界比（García - Esnaola和Peña于2009年发表在《应用数学快报》22(7):1071 - 1075）中的界更精确。
