地震数据中 速度模型的建立和层状介质的设定

学习线性分类器，可以自动识别两类数据点，数据点可以有交叉域，或者没有，共使用了三种方法。(Learning the self-learning process of linear classifier, and then design a linear two-class classifier and do some research based on the feature of linear classifier.)

使用Matlab的M文件实现的SVPWM程序，包含调制区和过调制区两个过程，文件包含主程序和子程序，经过测试可行。(Using Matlab M-file to achieve SVPWM program consists of two processes modulation region and over-modulation region file contains the main program and subroutines, tested feasible.)

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.)

切片干扰。切片干扰是一种新型干扰。该算法仿真了对线性调频的切片干扰。 (Slice interference. Slice interference is a new type of interference. The algorithm is simulated on the slice of linear frequency modulation interference)

经典的GPS原理书，有深度，并且有matlab实例(GPS classical principle of the book, depth, and have matlab examples)

说明：  该仿真模型是用来提取单机无穷大系统发生故障短路各线路三相电压的最大值(The simulation model is used to extract single machine infinite bus system short-circuit failure of the maximum three-phase voltage of each line)

说明：  数据挖掘经典算法matlab实现，补充代码！(Classical data mining algorithm matlab realize, supplementary code!)

说明：  一些关于信道编译码的Matlab源代码,国外一所大学的matlab编译码解答。(some of the channel codec Matlab source code, a foreign university Matlab encryption answer.)

该代码为gps软件接收机的跟踪环路的matlab实现程序，可以实现简单的gps跟踪环路的功能。(The code for the gps tracking software receivers realize matlab program loop, you can realize a simple loop gps tracking functions.)
