摘要
两网格方法与外推方法是求解偏微分方程的有效数值方法.将两网格方法与外推方法结合,构造了一类求解特征值问题的复合式外推两网格方法,可以得到更高精度的求解.数值实验验证了算法的有效性.
The two -grid method and the extrapolation method are effective numerical methods. By combining the two methods, this paper has constructed an extrapolation of the compound two - grid method for solving eigenvalue problems and for more accurate solutions. Numerical tests have proved its efficiency.
