最大流最小截问题，用ｍａｔｌａｂ编写的，ｒａｒ中有说明，较清晰(Maximum flow minimum cut problem, written with matlab, rar have stated more clearly)

凹边形判定算法，可用Matlab编程,也可用Mathematica软件编程(Concave gon determination algorithm, Matlab programming available, can also be used Mathematica software programming)

克里格法是地统计学的主要内容之一，从统计意义上说，是从变量相关性和变异性出发，在有限区域内对区域化变量的取值进行无偏、最优估计的一种方法；从插值角度讲是对空间分布的数据求线性最优、无偏内插估计一种方法。(Kriging method is one of the main contents of geostatistics. Statistically speaking, it is a method of unbiased and optimal estimation of regionalized variables in a limited area from the point of view of correlation and variation of variables; from the point of view of interpolation, it is a method of seeking linear optimum and unbiased interpolation estimation of spatial distribution data.

说明：  此算法是用遗传算法解决一元函数的最值问题(This algorithm is a function of genetic algorithm to solve the most value of a dollar problem)

说明：  QPSK（四进制相移键控）信号调制解调过程（经高斯信道）的仿真(QPSK (quaternary phase shift keying) signal modulation and demodulation process (by the Gaussian channel) of the simulation)

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％， 不加入噪声，进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)

这是简易的BPSK信号调制，把文件放入matlab的文件库中，通过在matlab的命令窗口直接调用功能函数并运行，可以直接看到仿真结果。(This is a simple BPSK signal modulation, the documents placed in a the Matlab file library, call function directly in the Matlab command window and run the simulation results can be seen directly.)

按照给定的差分格式编程实现求出数值解；结合格式的相容性和收敛性条件简单分析计算结果。(Numerical solution obtained in accordance with the given differential format programming combined format compatibility and convergence conditions simple analysis of the calculation results.)
