Fifty Years of Shannon Theory

C语言作的四色验证1．需求分析问题描述：证明了可以用不多于4种颜色对n个区域着色，而满足相邻的区域具有不同的颜色输入形式 ： 暂定最多50个区域，如需证明更多区域，修改#define S 50 即可；以整形形式输入（取值范围1-32767）用户需要证明的区域数目，相联的一对矩阵； 输出形式：以0和1输出关联矩阵，和以blue yellow orange pink形式输出每个区域相对应证明出的颜色；-C language does four colors confirm 1. demands analyses question description: Had proven may use not to be many to 4 kind of colors to n region coloration, but satisfies the neighboring region to have the different color input form: Establishes provisionally more than 50 regions, if must prove more regions, revise#define S 50 then; Region number (value scope 1-32767) the user needs to prove which by the reshaping form input, unites a pair of matrix; Output form: By 0 and 1 output incidence matrixs, with form outputs the color by blue yellow orange the pink which each region corresponds proves;

应用背景程序求解完全的二维N-S方程，考虑了粘性和导热。当来流Mach数为4时，计算结果与书上的结果一致，然而，我的程序不能计算Mach数为25的情况（即书中提供的另一种工况的比较结果），经过仔细检查，我认为自己的程序没毛病，可能是书中求解步长的公式给错了（eq.(10.16) in p.457），还望大家帮助检查一下。最后还要说明的是，该章在指导你写程序时，书上有些关键地方有印刷错误，会误导你，一定要小心。参考文献：Chapter 10, Computational Fluid Dynamics, The Basics with Applications, John D.
