摘要 讨论了方程Kx=y两步定常迭代的近似解,推导出滤波函数.通过适当地确定α,β的范围,证明此滤波函数是正则滤波函数,并给出此迭代的收敛阶及停止法则. The approximate solutions of equation Kx = y was solved by linear two-step stationary iterative methods. Filter function is a regularizing filter function by restricting α, β. Finally, the stopping criteria and the order of convergence were given.
