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。
These methods leverage fixed-point and weight-splitting schemes for computation. The study demonstrates the convergence of the proposed schemes to nonnegative solutions of the SARE in specific situations. Additionally, various numerical examples illustrate the effectiveness of these schemes in solving ...
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 is the Matlab m-file that ...

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- ...
The proposed method is based on expressing the particular solution of the governing equation in terms of an integral involving Greens function. Then, the KrasnoselskiiManns fixed-point scheme is implemented to an amended version of the resulting integral operator. The convergence of the iterative ...

Our implementation of a fixed-point iteration technique for the three-dimensional (3D) steady-state simulation of MOSFET devices is presented. The simulation program is employed to investigate narrow channel effects on the device current-voltage characteristics. Particularly, the effects of impact ...
