区三角
Examples
- Particularly for navier - stokes equation , we will compare the gmres methods with different preconditioned . we make some variances from the hss preconditioner ( [ 15 ] ) , that are ma1 - ma4 in our paper . comparing with block triangular preconditioner we will find that the cpu time for ma1 is the smallest
对navier - stokes方程的求解，我们重点是比较不同预条件的gmres方法，对基于对称，反对称分裂( hss )的预条件( [ 15 ] ) ，我们提出几种变形，本论文分别用m _ ( 1 ? m _ ( 4 )来表示，并用它们和约束预条件做比较，结果表明，在计算时间上m _ ( 1 )是最少的，最后我们对ep线性方程组的广义逆解的扰动分析的某些结果也通过数值实验给予验证。
