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。
Here, we will discuss a methodcalled fixed point iteration method and a particular case of this method called Newton'smethodMehmet KarakasS. Ishikawa, Fixed points and iteration method, Proc. Amer. Soc. 44 (1974) 147-150.

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 ...

I have the fixed point iteration x(i+1) = g(xi) where g(x) = 1 - 5x + 15/2x^2 - 5/2x^3. I've found the roots, so I know the guess cannot be near the roots else it will not diverge. But how do I choose a number, and moreso how do I show using matlab that it di...
看论文的时候出现了投影不动点迭代的概念,在网上搜索了一圈也没有看到太多相关的东西。 只看到了很多凸优化方面的不动点迭代内容,先粘个参考链接,学懂了前来补充~ 投影的概念和不动点迭代的结合 不动点迭代 不动点迭代的概念在第1个参考链接里描述的比较明确,梯度等于0 x与算子之间的关系,画图来看就是函数曲线...
