22 据理论中用于求取Jousselme证据距离案例

MATLAB下用最小二乘设计低通，高通，带通，带阻数字滤波器。(Using MATLAB m-file to design LP, HP, BP and BS fitlers based on Least-square algorithm.)

直接将秘密图像的高4bit隐藏在RGB载体图像的R,G,B层中所选的那一层的低4bit,并将秘密图像提取出来，最后显示。要求载体图像的大小大于等于秘密图像的大小，且秘密图像是二值或灰度图像(Directly to the secret image hidden in the high-4bit RGB vector images R, G, B layer, then a layer of selected low 4bit, and extracted secret image, the final show. Required size of the image carrier is greater than equal to the size of the secret image, and the secret image is a binary or gray image)

彩色圆环，按顺时针变化，红橙黄绿蓝靛紫红(Color circle, clockwise change, orange yellow purple indigo)

用差分方法计算带时变系数的波动方程,界面可视。(simulate the wave functions with time-varying coefficients)

首先一个是基于JAKE模型的多径衰落信道模型及性能分析。另外一个是OFDM系统中基于上述信道模型的性能分析。(JAKE first model is based on a multipath fading channel model and performance analysis. Another system is the OFDM channel model based on the above analysis of the performance.)

数据资料是数学模型与实际问题接轨的重要途径和手段，有时还可以直接从数据资料中发现规 律组建模型。数据分析和处理是统计学研究的主要内容，也是计算数学的工作领域，近年来随 着计算机科学的发展，对“海量”数据的分析形成了一门新的交叉学科“数据挖掘”。这一章仅 介绍用统计学的最小二乘法构造拟合数据模型，以及用计算数学的函数插值方法处理数据解决 实际问题。(Is a mathematical model of data integration an important practical problem with the ways and means, and sometimes directly from the data can also be found in the law of the formation model. Statistical data analysis and processing is the main research, but also work areas of computational mathematics, computer science in recent years, along with the development of the " mass" analysis of the data formed a new cross-disciplinary " data mining." This chapter describes only the structure with a statistical method of least squares fit data models, and computational mathematics and data processing function interpolation methods to solve practical problems.)

PCM编码,ASK,FAK,DPSK调制与解调(PCM encoding, ASK, FSK, DPSK modulation and demodulation.)

自编的倒频谱代码。倒频谱（信号）是信号频谱取对数的傅立叶变换后的新频谱（信号），有时候会称频谱的倒频谱(A cepstrum is the result of taking the Inverse Fourier transform (IFT) of the logarithm of the estimated spectrum of a signal)

基于BP_Adaboost的强分类器设计——公司财务预警建模(Design of strong classifier based on BP_Adaboost: modeling of corporate financial early-warning)

说明：  使用MATLAB的S函数来实现模糊控制查询表的计算，全部由程序实现，不使用FUZZY工具箱.(using MATLAB S function to achieve fuzzy control for the table, all by program, the non-use of fuzzy toolbox.)
