fft

用于计算流体力学中五类黎曼间断问题数值模拟(Program Used for five kind of Riemann problem in CFD)

512点FFT程序，分10级蝶形运算完成。(512-point FFT program, sub-10 butterfly to complete.)

matlab实现log算子，进行图像边缘的提取(matlab realize log operator to extract image edge)

说明：  使用matlab仿真自适应光学系统，包括变形镜，哈特曼传感器等，有详细的使用说明，是英文的(Matlab is used to simulate adaptive optics system, including deformable mirror, Hartmann sensor, etc)

说明：  该程序实现的了2x2的mimo系统收发。运行system程序，可看到接受端的误码率曲线，星图。(the process of the realization of the 2x2 MIMO transceiver system. Operating system procedures, we can see the receiving end of BER curves, star maps.)

With PRP conjugate gradient method for solving unconstrained problem

机器学习中的垃圾邮件分类程序，用matlab做的。从以下链接下载垃圾邮件数据（spam data）：(数据已下载，放在spambase.zip) http://www-stat.stanford.edu/~tibs/ElemStatLearn/index.html 该数据包含57个邮件信息相关的变量，每条邮件可以被分类为垃圾邮件（Y=1）和非垃圾邮件（Y=0）。输出Y的值在文件中每一列的末尾。练习的目标是要预测电子邮件是否为垃圾邮件。 (Machine Learning spam classification procedures, using matlab to do. Data (spam data) from the following link to download the junk mail: (data has been downloaded, put spambase.zip) http://www-stat.stanford.edu/ ~ tibs/ElemStatLearn/index.html The data includes 57 e-mail messages related variables, each message can be classified as spam (Y = 1) and non-spam (Y = 0). Y value of the output end of each column in the file. The goal is to predict exercise email is spam.)

这个程序是关于matlab7中GADS工具箱的使用例程，比较有特点。(This process is about the GADS toolbox matlab7 in the use of routines, the more characteristics.)

用预测算法控制三相逆变器，该方法简单易懂，适合入门学习(With a prediction algorithm control three-phase inverter, the method is simple and easy to understand, suitable for beginners to learn)
