音乐分类的几种方法，解决传统音乐风格划分的模糊性。(Music classification are several ways to solve the traditional music style by vagueness.)

Image Compression A collection of simple routines for image compression using different techniques. BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function conv2fft performs a 2D FFT-based convolution. Type help conv2fft on MATLAB command window for more informations.

很实用的一个OFDM仿真程序，OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图，将每个子信道上的数据，映射到星座图点的复数表示，转换为同相Ich和正交分量Qch。(A very practical OFDM simulation program, OFDM the BPSK, QPSK, 16 qam, 64 qam4 kind of modulation method. According to the constellation diagram, each will be the data on the channel, the plural of constellation is mapped to a point, said into in-phase Ich and quadrature Qch. )

OFDM Simulation Using Matlab 里面附有详细关于OFDM实现的说明，并给出了MATLAB实现代码(OFDM Simulation Using Matlab inside with detailed description on the OFDM realize, and realize given MATLAB code)

说明：  最小二乘支持向量机（来自于互联网，本人测试过，好使）(Least squares support vector machine (from the Internet, I tested, so that))

说明：  老外的电机学教材，最为重要的是有相应的MAtlab代码，每一章都有，十分详细，学习电机的必备工具书，文件是在太大，此处上传chap5的源码(Foreigners motor learning materials, the most important thing is there is a corresponding MAtlab code, each chapter has a very detailed study of the motor necessary books, documents are too large to upload chap5 source code here)

matlab中画地震图件的子程序源代码，对物探人员很有用。(Matlab in picture seismic datum of source code, useful for geophysical prospecting personnel.)

主要利用粒子滤波进行人体跟踪,能很好地进行人体跟踪(The main use of the particle filter for human body tracking, can be used for human body tracking)
