摘要
研究第二类Wiener-Hopf积分方程的高精度数值解法.复合Nystr?m-Clenshaw-Curtis(NCC)求积方法被引入,预处理共轭梯度法被用于求解离散方程组,数值结果用于说明算法的有效性.
Highly accurate numerical methods for the solution of Wiener-Hopf integral equations of the second kind are studied. Composite Nystr？m-Clenshaw-Curtis（NCC） quadratures are introduced to discretize the integral equation and the preconditioned conjugate gradient method is applied to solve the corresponding discretization linear system. Numerical results are presented to illustrate the effectiveness of the algorithms.
