Description: 《ＭＣＳ－５１单片机实用子程序库（９６年版）》周航慈
目前已有若干版本的子程序库公开发表，它们各有特色。笔者在1988年也编制了两个
子程序库（定点子程序库和浮点子程库），并在相容性、透明性、容错性和算法优化方面作了一些工作。本程序库中的开平方算法为笔者研究的快速逼近算法，它能达到牛顿迭代法同样的精度，而速度加快二十倍左右，超过双字节定点除法的速度。经过八年来全国广大用户的实际使用，反馈了不少信息，陆续扩充了一些新的子程序，纠正了一些隐含错误，成为现在这个最新版本。（转）-"MCS-51 microcontroller practical Subroutine Library (96)" Hang Zhou chee There are a number of versions of the son the procedure is published their own characteristics. The author in 1988 also produced two subroutine library (fixed-point and floating-point subroutine library son-Treasurer), and compatibility, transparent, fault tolerance and optimization algorithm has done some work. The procedures for the open square algorithm for the rapid study author approximation algorithm, it will reach Newton iteration of the same precision, and the speed around 20 times, more than double byte sentinel division of speed. After eight years of the country's actual use of user feedback a lot of information, gradually expanding the number of new subroutine, corrected some mistakes implied

Description: 迭代法是解线性代数方程组的另一类方法，特别适用于解大型稀疏线性方程组。它的基本思想是针对求解问题预先设计好某种迭代格式，从而产生求解问题的近似解迭代序列，在迭代序列收敛于精确解的情况下，按精度要求取某个迭代值作为问题解的近似值。迭代法具有原始系数举证始终不变，算法简单，编写程序较方便，所需存储单元较少的优点。-iterative method was the linear algebraic equations of the other methods, particularly applicable to the large sparse linear equations. The basic idea is to solve the problem in advance against the design iteration some good format, thereby creating problems for the approximate solution of iterative sequence, the iterative sequence converges to the exact solution, precision demanded by a certain value as a question iterative solution approximation. Iteration with the original proof coefficient remains unchanged, the algorithm is simple, the preparation process more convenient, less required storage unit advantages.
