A fingerprint recognizing system is built with two principal components: the fingerprint admin istrator and the fingerprint recognizer. Fingerprints are identified by their special features such as ridge endings, ridge bifurcation, short ridges, and ridge enclosures, which are collectively called the minutiae.

说明：  带约束算子的粒子群算法，用于matlab环境，对于搞研究的教师有很大帮助(Operator Constrained Particle Swarm Optimization for the matlab environment, engage in research for teachers are very helpful.)

信号产生和fft变换分析 信号通过switch函数选择产生(Signal generation and fft transform analysis of the signal generated by switch function selection)

自适应TV去噪，是一种自适应滤波算法，处理噪声效果良好，适合编程参考(TV adaptive de-noising, is an adaptive filter algorithm processing noise effect is good for programming reference)

粒子滤波通过随机采样生成粒子，计算随机变量的后验分布(Particle filter generates particles by random sampling and calculates the posterior distribution of random variables.)

这是一个非常好的mpsk仿真程序。其中包括BPSk，QPSK，8PSK,16PSK的BER和EB/N0曲线，SER和ES/N0曲线。(This is a very good MPSK simulation program. Including BPSk, QPSK, 8PSK, 16PSK the BER and EB/N0 curve, SER and ES/N0 curve.)

节点总数目N； 平均连接度α 边的平均长度β 两点间长度d(i,j) 节点间最长的边的长度L 两点的连接概率p(i,j) (The total number of nodes N average connectivity α β average length sides between two points length d (i, j) between nodes longest side length L connecting two points of the probability p (i, j) )

是美国统计学家萨尔斯伯格以“女士品茶问题”为切入点所著的一部关于统计学历史与变革的书，以一种全新的视角带领读者进入统计学的世界，体会统计学带给哲学观、宇宙观的变革(Salthe Berg statistician USA to Lady Tasting Tea problem as the starting point of a statistical history and change of the book, with a new view and lead the reader into the world of experience of statistics, statistics to philosophy, cosmic view change)

说明：  电力系统拓扑分析、孤岛数，关联矩阵法把主接线的节点和母线的每一进出线连接点作为拓扑图的节 点，把开关元件作为拓扑图的支路，建立节点．支路关联矩阵表示电网的基本拓 扑结构。然后定义矩阵“与．或’’乘法运算，利用连通性的传递性质实现对电力 网络结构的辨识。(In the incidence matrix method, the node of the main connection and the connection point of each incoming and outgoing line of the bus are taken as the node of the topology diagram, and the switching element is taken as the branch of the topology diagram to establish the node.The branch correlation matrix represents the basic topology structure of the power grid)

可以用于二维图像评估程序，若稍微加改进可以作为识别方法(Two-dimensional image can be used in the assessment process, if a little can add to improve the method as a means of identification)
