In this paper, we establish nonstationary USSOR multisplitting method and USSOR multisplitting method for solving H-matrix linear system Ax = b , which has wide application. Moreover, convergence domains of nonstationary USSOR multisplitting method and USSOR multisplitting method are studied when A is a nonsingular H-matrix. Numerical examples are given out to show our new convergence domains are wider and effectiveness.
