ICA极大似然估计的自然梯度法仿真实例，并计算了串音误差( An experiment of ICA by MLE,including psnr)

音频无损压缩程序，加入随机噪声，利用前向预测算出预测误差，再用熵编码，组帧，最后解码(Lossless audio compression program, by adding random noise to the prediction error is calculated using the forward prediction, and then entropy coding, framing, and finally decoding)

Lorenz系统的李雅谱诺夫指数，指数谱，大家多支持下哦(very good dajia juedebucuojiu zhichi xia )

邻接灰度共生矩阵（NGLDM）特征提取程序(Neighboring Gray-Level Dependence Matrix Feature Extraction)

Field Ⅱ超声成像代码，可以进行单个孔径成像和合成孔径成像、加权和不加权仿真。(The calculation of point spread functions is done by placing a point in front of the transducer and then sweeping the beam over the point. This gives the point spread function of the imaging system. Field II can make this calculation for a number of points simultaneously and thereby reveal the dynamic focusing properties of the imaging system. A point phantom has been made for this purpose. It consists of a number of point targets placed with a distance of 5 mm starting at 15 mm from the transducer surface)

说明：  机器人matlab编程课本的程序，每一个程序都很好。(The Program of Robot Matlab Programming Textbook)

The Shaper is implemented as a state machine for code production and integration in embedded systems. Shaper gets active on a rising edge of Trigger , filtering out the fast dynamic of the target in which excites all the plant modes. param.mat plant.mdl shaper.mdl shaperScan.m

图论研究中的图着色问题的matlab程序，非常好用啊！(Study of Graph Theory Graph Coloring Problem of matlab program, very easy to use ah!)

说明：  ofdm的时域仿真代码，matlab下正常。(ofdm s time domain simulation code with matlab,it s works well.)
