A New Type of Preconditioned Iterative Methods for Z-matrices

  • A new type of preconditioned iterative methods for solving a linear system Ax=b are presented,some of related convergent results are proved.Some numerical examples illustrate that the convergence rate of the new preconditioned method proposed is superior to the classical Gauss-Seidel iterative methods.
