基本克里金算法，用于代理模型的参数计算，解决可靠性计算的通用matlab方法(Basic Kriging algorithm. The model is used to calculate the parameters of the agent model and to solve the general matlab method for reliability calculation)

瑞利衰落能有效描述存在能夠大量散射無線電訊號的障礙物的無線傳播環境。若傳播環境中存在足夠多的散射，則衝激訊號到達接收機後表現為大量統計獨立的隨機變量的疊加，根據中心極限定理，則這一無線頻道的衝激響應將是一個高斯過程。如果這一散射頻道中不存在主要的訊號分量，通常這一條件是指不存在直射訊號（LoS），則這一過程的均值為0，且相位服從0 到2π 的均勻分布。即，頻道響應的包絡服從瑞利分布。

三乘四二维数组 求所有元素中最大值，这个程序很简单的，大家看看就好(Three in four two-dimensional array for all elements in the maximum)

适用于本人开发的抽号器WindowsFormsAppkication.rar。 可以运行后在in.txt中第一行输入总人名数，之后从第二行开始，每一行输入一个人名。之后运行程序（eze等同于exe），会生成Form1.cs，用记事本打开后复制到原Form1.cs进行替换。可以应对多种情况。(I developed suitable for pumping number is WindowsFormsAppkication.rar. After the run in the first row in.txt enter the total number of names, and then start from the second row, enter a name for each row. After running the program (eze equivalent exe), will generate Form1.cs, copy after use Notepad to open Form1.cs to replace the original. You can respond to a variety of situations.)
