A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case.Polyalphabetic substitution ciphers are useful because the are less easily broken by frequency analysis, however if an attacker knows for instance that the message has a period n, then he simply can individually frequency analyze each cipher alphabet. The number of letters encrypted before a polyalphabetic substitution cipher returns to its first cipher alphabet is called its period. The larger the period, the stronger the cipher. Of course, this method of encryption is certainly not secure by any definition and should not be applied to any real-life scenarios.

对数据进行预处理的程序，希望用本程序把这些到期收益率（标准期限）数据拿出来组成一个数据集以备分析之用。(Data pretreatment procedures, hope to use this procedure to these yield to maturity (standard period) data show the formation of a data set for analysis.)

spectrum sensing is used for communication purpose. Matlab code is utilized for detecting signal by using energy detection noise.

。本书首先讲述了MATLAB语言程序设计基础，然后分别介绍了符号计算在微积分和复变函数两门大学数学基础课程中的应用，接着系统的介绍了线性方程组、非线性方程与最优化方法、特征值与特征向量、插值与函数逼近、估计方法和数据拟合、积分计算、常微分方程的数值方法。从实用角度考虑，本书许多章节都给出了一些数值分析的应用范例，并在最后一章单独介绍了一些综合性较强的数学建模问题(This book starts by describing the basis of MATLAB programming language, and then introduced the symbolic computation in calculus and complex functions based on two college courses in applied mathematics, and then introduced the system of linear equations, nonlinear equations with the most optimization method, eigenvalue and eigenvector, Interpolation and function approximation, estimation and data fitting, integral calculation, numerical methods for ordinary differential equations. From a practical point of view, many of the chapters the book gives some numerical analysis are examples of the application, and separate in the final chapter describes some of the more integrated mathematical modeling)

用FAMALE.TXT、MALE.TXT和/或test2.txt的数据作为本次实验使用的样本集，利用C均值和分级聚类方法对样本集进行聚类分析，对结果进行分析，从而加深对所学内容的理解和感性认识。(Use FAMALE. TXT, MALE. TXT and/or test2. TXT data as the use of the samples, using C mean and hierarchical clustering method of samples of clustering analysis, the analysis of the results, so as to deepen the understanding of the content of study and perceptual knowledge.)
