讨论求解线性方程组的定常化chebyshev加速迭代法,给出了该方法的若干收敛性条件,通过数值算例比较了chebyShev加速定常迭代法与非定常迭代法的收敛速度,计算结果表明二者是相当的。
The paper discusses the stationary Chebyshev acceleration method which is applied to the numerical solution of algebraic linear systems, and shows some conditions of convergence. Comparing the convergent rate the stationary iterative method with the unstationary iterative method by several examples, we find the same convergent rate between the two methods.
