The class of \(\{P_1,P_2\}\)-Nekrasov matrices, defined in terms of permutation matrices \(P_1\) and \(P_2\), is a generalization of the well-known class of Nekrasov matrices. In this paper, some computable error bounds for linear complementarity problems (LCPs) of \(\{P_1,P_2\}\)-Nekrasov matrices are given, which depend only on the entries of the involved matrices and can be used to obtain the perturbation bounds of \(\{P_1,P_2\}\)-Nekrasov matrices LCPs. Besides, some sufficient conditions ensuring that the subdirect sum of \(\{P_1,P_2\}\)-Nekrasov matrices lies in the same class are also provided.

根据置换矩阵\（P_1 \）和\（P_2 \）定义的\（\ {P_1，P_2 \} \） -Nekrasov矩阵的类别是对Nekrasov矩阵的知名类别的概括。本文给出了\（\ {P_1，P_2 \} \）- Nekrasov矩阵的线性互补问题（LCP）的一些可计算误差界，这些误差界仅取决于所涉及矩阵的项，并且可用于获得\（\ {P_1，P_2 \} \）- Nekrasov矩阵LCP的摄动界。此外，还提供了一些充分的条件，以确保\（\ {P_1，P_2 \} \）- Nekrasov矩阵的子直接和位于同一类中。
