We discuss the problem of finding approximate solutions of the equation f (x) 0 (1)In some cases it is possible to find the exact roots of the equation (1) for example whenf (x) is a quadratic on cubic polynomial otherwise, in general, is interested in findingapproximate solutions...
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。
iteration固定点迭代fixedpointexample Fixed-Point Iteration Example We wish to find the root of f(x) = x 3 +5x −5 that is in the interval [0, 1] to 6 decimal places. We perform the iteration x n+1 = g(x n ) = (5 −x 3 n )/5 , starting with x(0) = 0.75 . Here...

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...
FIXED POINT ITERATION FOR LOCAL STRICTLY PSEUDO-CONTRACTIVE MAPPING XINLONG WENG (Communicated by Paul S. Muhly) 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- ...
Consider, for example, a fixed point iteration scheme to compute roots of an equation in one or more variables. It might so happen that for one of the several roots, the scheme could come across 0/0 or a division of a finite nonzero number by 0 or square-root of a negative number....
