This paper is concerned with a modified version of the generalization of Hermitian and skew-Hermitian splitting iteration (MGHSS) to solve the non-Hermitian positive definite linear systems. The corresponding inexact MGHSS (IMGHSS) method is developed by employing some Krylov subspace methods as its inner process. Numerical examples are reported to confirm the efficiency of the proposed methods.
