In this paper we establish a modified general modulus-based matrix splitting iteration method for solving the large sparse linear complementarity problems of H_+-matrix and present the convergence analysis. In addition, the optimal parameters are considered under the given methods and we supplement the proof of equivalence of(z,r) from Methods3.1 and 3.2 in [2] and the solution of the original linear complementary problem LCP(q, A).Finally, we give a numerical example, which illustrates that the modified method is efficient.
