摘要
Gauss-Seidel迭代法是经典的迭代法,通过提出一种新的预条件因子,证明了在非奇异M-矩阵下该预条件加速了迭代法的收敛性。最后给出数值算例说证明:该预条件迭代格式优于通常的预条件法。
Gauss-Seidel iteration is the classic iterative method. In recent years a variety of preconditions Gauss-sei-del iterative methods have been raised. In this paper, we first present a preconditions factor and then prove the accelerated convergence of the iteration method by the preconditions under the nonsingular M-matrix. Numerieal examples show that the precondition is superior to the usual preconditions law.
