说明：  层次分析法是对一些较复杂、较模糊的问题作出决策的简易方法，它特别适用于那些难于完全定量分析的问题。 层次分析法是一种将决策者对复杂系统的决策思维过程模型化、数量化的过程。应用这种方法，决策者通过将复杂问题分解为若干层次和若干因素，在各因素之间进行简单的比较和计算，就可以得出不同方案的权重，为最佳方案的选择提供依据，因此层次分析法常应用分析评价定性量化问题。(Analytic Hierarchy Process is an easy way for some of the more complex, the more obscure the issue of decision-making, it is particularly difficult for those who complete quantitative analysis of the problem. Analytic Hierarchy Process is a method of decision-makers of complex systems thinking process modeling, quantitative process. Application of this method, decision makers through the complex problem into several levels and a number of factors, among the factors that make simple comparisons and calculations, different scenarios can be drawn on the right weight, provide the basis for selecting the best solution, so Analytic Hierarchy Process is often used to quantify the problem of qualitative analysis and uation.)

说明：  40KHZ局部放电超声信号源模拟仿真，四种衰减形式：单指数、单指数振荡、双指数、双指数衰减震荡(Simulation of 40KHz PD ultrasonic signal source, four attenuation forms: single index, single index oscillation, double index, double index attenuation oscillation)

说明：  MATLAB在水库调洪计算中的应用，使得水库调洪问题简单。(MATLAB in the calculation of reservoir flood of applications, makes a simple reservoir flood problems.)

说明：  光纤LP01模式,光纤模式计算，纤芯模式，有效折射率(Fiber LP01 mode, fiber mode calculation, fiber core mode, effective refractive index)

说明：  模式 识别 matlab程序 很不错的，相信我哦 (Pattern recognition matlab program)

这个 matlab 代码仿真了M-QAM的传输。M的取值不同，调制方式分别为4QAM，16QAM，64QAM等。传输信道为AWGN信道，能出误码率曲线(Digital Unit Impulse Discrete Harmonic Signals and their Linear Combination Harmonic Signal with Exponential Envelope. Periodic Sequence of Rectangular Impulses Mixture of Harmonic Signal and White Gaussian)

详细的介绍了matlab实用技术的方法和工作原理(Describes in detail the methods and practical techniques matlab works)

主要详细的讲解MATLAB的各种的使用和说明；为MATLAB的入门和提高有一定的帮助。(Main detailed explanation of all sorts of use of MATLAB and specification, For MATLAB introductory and improve has certain help.)
