采用卡尔曼滤波方法对AR（3）时间序列模型进行校正，关键句有说明，(Kalman filter correction AR (3) time series model, described key sentence)

利用神经网络对输入的Ｍ序列进行线性离散系统辨识，及其改进算法(The use of neural network input M-sequence of linear discrete-time system identification, and its improved algorithm)

说明：  通信系统离散信道仿真，散射、离散多径信道衰落模型mfiles(Communication system discrete channel simulation, scattering/discrete multipath fading channel matlab mfiles)

matlab中文件的读写，可以将你想要的数据通过文件打印在sin.txt的文件中，适合初学者。(read and write files in matlab, you can file through the data you want printed on sin.txt file, suitable for beginners.)

用MATLAB写的，用Prim算法找出图中的最小支撑树，文件中有例子，有计算的结果，一看便懂。(Written in MATLAB, with the minimum support tree in the Prim algorithm to find a figure, file example, with the result of calculation, a see will understand.)

很详细的matlab程序 最小二乘法最优化程序(Very detailed procedures matlab least squares optimization procedures)

带电圆环的电势分布图，利用matlab求解带电圆环的电势分布图(Charged electric potential distribution ring)

应用matlab开发的ofdm源代码，其中和QAM调制方式做了比较，内含部分说明文档(Application development of OFDM matlab source code and QAM modulation which has done a comparison, contains some documentation)

此matlab代码用于削减并消除图片中的block，提高图片质量。Deblock使用小波变换消除block，DeBlocking2通过计算熵，确定每个block的信息量，来消除block(This matlab code is for diluting and removing artifacts in images, upgrading the images. DeBlock applies wavelet to deblock and DeBlocking2 deblocks by calculating entropy, classifying amount of information, in each block.)
