摘要:
将二维延拓Kantorovich法推广到三维延拓Kantorovich法时,通过大量数值算例发现了一个新现象,即如果采用简单形式的三维延拓Kantorovich法,那么会遇到迭代不收敛的数值困难。对此数值现象进行定性分析,可得出结论:三维延拓Kantorovich法并不是二维延拓Kantorovich法的简单推广,二者有着本质的不同。更多还原
Abstract:
When two-dimensional extended Kantorovich method is introduced to three-dimensional ex?tended Kantorovich method, a large number of numerical examples reveals a new phenomenon: if the simple three-dimensional extended Kantorovich method is used, the numerical difficulty of iteration non-convergence will occur. Qualitative analysis on this numerical phenomenon indicates that three-dimensional extended Kantorovich method is not a simple introduction of two-dimensional extended Kantorovich method, and they are different in nature.
