Sažetak
In this paper, based on the shift splitting of the
coefficient matrix, a generalized two-sweep shift splitting (GTSS)
method is introduced to solve the non-Hermitian positive definite
linear systems. Theoretical analysis shows that the GTSS method is
convergent to the unique solution of the linear systems under a
loose restriction on the iteration parameter. Numerical experiments
are reported to the efficiency of the GTSS method.
