这个zip文件中包含的原则和双方的扩展卡尔曼滤波（EKF）和全球定位系统（GPS）算法简要说明。它的主要目的是提供一个相对容易实现的扩展卡尔曼滤波，在我们使用的输入函数的形式，而不是禁止函数处理符号表达式。它也可作为一个简要介绍了卡尔曼滤波算法GPS和学习它的意思。在为EKF的例子，我们提供的原始资料，同时使用的定位扩展卡尔曼滤波和最小二乘法的任务和解决方案。 有四个M文件和两个数据文件。 Extended_KF.m包含EKF的函数体。另一些功能和GPS的示例数据文件。(This zip file contains a brief illustration of principles and algorithms of both the Extended Kalman Filtering (EKF) and the Global Position System (GPS). It is designed primarily to provide a relatively easy-to-implement EKF, in which we use symbol expressions as the form of input functions rather than the forbidding function handles. It also serves as a brief introduction to the Kalman Filtering algorithms for GPS and a mean of learning it. In the example for the EKF, we provide the raw data and solution for the positioning task using both EKF and the Least Square method. There are four m files and two data files. Extended_KF.m contains the function body of the EKF. Others are functions and data files for the GPS example.)

介绍时频分析的基本理论和在工程中的应用方法，介绍了MATLAB时频分析工具箱的用法。(Introducing the basic theory and application of frequency analysis methods in engineering, describes the time-frequency analysis MATLAB toolbox usage.)

对于噪声中的正弦信号，通过周期图法、AR模型法、Pisarenko谐波分解算法、MUSIC算法和ESPRIT算法进行频率估计，使用N=128个数据样本进行估计. (By the periodogram method, AR model method, the Pisarenko harmonic decomposition algorithm, MUSIC algorithm and the ESPRIT algorithm for sinusoidal signals in noise, frequency estimation, N = 128 data samples to estimate.)

基于SVM的快速极小化SMO化算法程序，程序清晰易懂，易理解，可读性强，希望对同行有所帮助 (SVM-based fast minimization algorithm SMO program, the program clear and easy to understand, easy to understand, readable, and want to help peers)

说明：  声明：本程序仅交流用，所以调试时用两颗棋子就可以赢(Disclaimer: This procedure only exchange with, so debugging can win with two pieces)
