说明：  用来解决压缩感知里求解优化问题的算法matlab代码(solves the minimization problem. min_u ||u||_1+ lambda ||a*u- f||_2^2. algorithms are based on greedy coordinate descent and the bregman iterative method. matlab 7.5 (r2007b) image processing, mathematics, optimization, resconstruction . )

MATLAB仿真永磁同步电机直接转矩控制，传统滞环+开关表控制，仿真效果很好(The direct torque control of permanent magnet synchronous motor is simulated by MATLAB, and the traditional hysteresis plus switching table control has a good simulation effect.)

这是一个用matlab来实现的QAM,QPSK程序，可显示星象图，调制解调的信号波形和频谱波形(This is a matlab achieved by QAM, QPSK procedure shows astrology chart, modulation and demodulation of the signal waveform and spectrum waveform)

该文件实现了将医学图像从dicom格式转换为bmp格式，是医学图像处理中至关重要的一步。(The document will be achieved medical images from dicom format to bmp format medical image processing is a crucial step.)

用EWMA（garch（1，1））模型进行计算，rolling window的形式(use the method of rolling window size equals to 250, adopt EWMA model which also calls Garch(1,1) to calculate the Value at Risk)

三维空间离散点的曲面拟合,以及散点图做法(Three-dimensional surface fitting discrete points, and scatter plots practice)

说明：  基2fft的matlab程序，是比较简单的一种算法(2fft the matlab-based procedures, is a relatively simple algorithm)

说明：  watterson信道matlab仿真,瑞利衰落。。。。(This example shows how to simulate High-Frequency (HF) ionospheric channels, based on the models described in Recommendation ITU-R F.1487. In particular, it shows how to simulate the general Watterson channel model, and other simplified channel models used in the quantitative testing of HF modems. It makes use of the Rayleigh multipath fading channel object and the Gaussian and bi-Gaussian Doppler structures from Communications System Toolbox.)

是最新MATLAB工程应用的代码，都是代码在里面，很值得鉴赏(Engineering applications is the latest MATLAB code is the code inside, it is worthy of appreciation )
