[数学计算] 信号检测贝叶斯

使用Matlab编程,对教材74页例3.3.1进行编程仿真。其中,正电压A的值、噪声方差值、每个码元周期内的采样点数N自行设定(可设置为可调的变量)。噪声值可使用Matlab中产生高斯随机数的函数来进行仿真。贝叶斯检测判决式中,先验概率P(H1)=P(H0),判断错误的代价因子设为1,判断正确的代价因子设为0. 按照上述参数的设定进行仿真,实现对仿真数据的贝叶斯检测判决;循环生成仿真数据,并进行判决结果的统计,即记录判决正确的次数,估计正确判决的概率。
The use of Matlab programming, teaching materials 74 pages of 3.3.1 programming simulation. Among them, the value of positive voltage A, the variance of noise, the number of sampling points in each symbol cycle (N) can be set by itself (adjustable variable). Noise values can be simulated using the function of generating Gauss random numbers in Matlab. In the Bias detection decision, the prior probability P (H1) =P (H0), the factor of error judgment is set to 1, and the correct cost factor is set to 0. According to the simulation parameters and realize the judgment of Bayesian detection simulation data; generating cycle simulation data, statistics and decision, which records the correct number of judgment, the estimated probability of correct decision.

配电网辐射网前推回代潮流计算程序:前推回代法在配电网潮流计算中简单实用,所有的数据都是以矢量形式存储,因此节省了大量的计算机内存,对于任何种类的配电网只要有合理的R/X值,此方法均可保证收敛。而且,前推回代法的收敛阶数为一阶,因此它也具有较好的收敛稳定性。比较而言,前推回代法充分利用了网络呈辐射状的结构特点,数据处理简单,编程简单,没有复杂的矩阵运算,计算效率高,占用计算机的资源很少,具有较好的收敛性,广泛用于在实际配电网中,可称是求解辐射状配电网潮流问题的最佳算法之一。
With forward and backward substitution flow calculation grid Radiation Network program: front and backward substitution method in the distribution power flow calculation is simple and practical, all the data are stored in vector form, thus saving a lot of computer memory, for any kind of distribution network, as long as there is a reasonable R/X value, this method can be guaranteed to converge. Moreover, forward and backward substitution method convergence order for the order, so it has a good convergence stability. Comparison, the forward and backward substitution method take full advantage of network radiating structural features, data processing, programming is simple, not complex matrix operations, computationally efficient, very few take up the computer' s resources, has better convergence , widely used in the actual distribution network is one of the best algorithm for solving the radial distribution power flow problem.

[数学计算] IntersectionPointOfTwoLines

该代码绝对本人原创,可根据两打直线的四个端点坐标求解交点,并判断交点为实交点或虚交点,若两直线重合或平行,则返回值为FALSE: 以下代码为求交点的函数,使用方法: rtn=InterPointTwoLine(直线A起点X,直线A起点Y,直线A终点X,直线A终点Y, 直线B起点X,直线B起点Y,直线B终点X,直线B终点Y, 返回的交点X,返回的交点Y,交点类型) 有交点时该函数返回值为True,平行或重合时返回False 最后一个参数(Inter_Type)是交点类型: InterPointType=1 实交点 InterPointType=-1 虚交点 InterPointType=0 无交点此时函数的返回值同时为False 覃东 (C)测量员网 http://www.SurMap.com 2009-08-01 23:06

想加密自己的软件,看过一些软件的作法,思路如下: 1、用户安装后,得出本机的机器码(硬盘的序列号,不想用网卡,因为很多机器没有网 卡)。生成机器码代码 2、用户将该机器码EMAIL给我,我用该机器码生成一个注册码,发送给用户。注册码生成 代码 3、用户在程序中输入该注册码,程序逆算该注册码,与机器码核对,查看是否相符。注册 码逆算、核对代码, 4、如果用户安装后没有得到注册码,在N天后部分功能不可用。不要太容易被改(虽然说 安装后也只有少部份功能能用)。时限功能代码,
