计算孔口应力集中的计算复变函数方法。本人自己编的程序，可读性比较差。(Calculation of stress concentration calculation orifice complex variable function method. I own procedures, a relatively poor readability.)

对支票印鉴图像在HSV颜色模型下，根据设定的阈值对印鉴进行提取(Seal on the check image in HSV color model, based on the threshold of the seal set to extract)

turbo码的MATLAB simulaiton 采用硬输出判定 支持qpsk (turbo codes using MATLAB simulaiton qpsk hard output decision support)

（1）通过Simulink创建仿真模型；（2）配置相关RTW（Real-Time Workshop）参数；（3）通过RTW（Real-Time Workshop）自动生成C代码文件，并理解主要文件、接口函数和变量的意义；（4）在Visual C++中将生成的C代码作适当修改，编译运行并分析结果。((1) created by Simulink simulation model (2) configuration related to RTW (Real-Time Workshop) parameters (3) RTW (Real-Time Workshop) automatically generate C code files, and understand the main document, interface functions and variables significance (4) Visual C++ generated C code will be modified as appropriate, compile, run and analyze the results.)

横向各相同性介质的各个弹性系数，方便进一步计算其它弹性性质(the elastic properties of TI media)

此函数是循环平稳过程的相关函数，代码简明，是初学者学习的好资料(This function is the correlation function of stationary process cycle, the code simple, is good information for beginners to learn)

说明：  MATLAB在中值滤波改进算法中的应用,这里有一个关于自适应中值滤波的简单程序。(MATLAB in the median filter to improve the algorithm, there is an adaptive median filter on a simple procedure.)

传统的DOA估计算法，如MUSIC、ESPRIT算法，都是在假设信号没有相干的情况下求解的，一旦信源信号具有相干性，估计性能会急速下降，所以提出了空间平滑的算法，解决相干信号的波达估计！(The traditional DOA algorithms, such as MUSIC, ESPRIT algorithm, is under the assumption that the signal is not coherent case solving, once the source signal with coherence, estimation performance will fall, so put forward spatial smoothing algorithm, to solve the coherent signal estimation of direction of arrival!)
