求解f(x)=0还是很有用的,具体应用此不做讨论。这里将使用一系列专题阐述求解f(x)=0的各种方法。此次先讨论固定点迭代法(Fixed Point Iteration)。 下面先直接给出解法,后面再对原理进行阐述。 【问题描述】 已知f(x)=0,求使等式成立的x的值。
iterative methodfluid mechanicsnumerical solutionsIn this article we study the convergence of an iterative method recently proposed in Bewley et al. (Bewley, T.R.; Temam, R.; Ziane, M. A General Framework for Robust Control in Fluid Machanics. Phys. D 2000, 138(34), 360392) for the ...
Abstract. A fixed point of the local strictly pseudo-contractive mapping is obtained as the limit of an iteratively constructed sequence with an error esti- mation in uniformly smooth Banach spaces. This paper has been motivated by a paper by C. E. Chidume [2], in which ...
