图像特征提取以及匹配，sift代码。可用于图片检索中，同比SURF，其算法可以较好的识别图像中文字(Image feature extraction and matching, sift the code. Can be used for image retrieval, up by SURF, the algorithm can better identify the image text)

说明：  一个很有用的函数，功能是产生规定字长以及规定汉明重量的码字，常用于channel coding开发(A useful function, function is to have the provisions of word length and weight of the provisions of Hamming code word, commonly used in the development of channel coding)

基于matlab的数值计算试验程序。equ_direct，equ_iter，interpolation等(based on the numerical calculation Matlab testing procedures. Equ_direct, equ_iter, interpolation, etc.)

变步长LMS滤波器做系统辨识，有详细注释，课运行(Variable step size LMS filter to do system identification, detailed notes, classes run)

一维非稳态流动换热的matlab程序，流体和固体温度都在变化，时间和长度方向。(One-dimensional unsteady flow and heat transfer matlab procedures, fluid and solid temperatures are changing, time, and length.)

二维的克吕金插值，适用于地学类等领域，使用方便(Two-dimensional krig interpolation, applied geosciences)

应用MATLAB语言处理数字信号与数字图像，里面 有matlab调用c的方法(Application of MATLAB language processing digital signal with the digital image, which has matlab call method c)

【matlab编程代做】基于k-means算法 可以作为参考使用学习([Do] matlab program generation based on k-means algorithm can be used as a reference study)

分布式lms算法，传感器网络，仿真通过，可以运行的(Lms distributed algorithms, sensor networks, through simulation, can run)

把区域划分成矩形网格，找到每个网格的中心点，把每个网格当做一个圆环计算每个圆环的磁场，然后调用linprog函数就求出场分布了。不要求你把线圈矩形化，也不要求屏蔽场。(The region is divided into rectangular grids and the center points of each grid are found. Each grid is used as a circle to calculate the magnetic field of each ring, and then the field distribution is called by the linprog function. It does not require you to rectangle the coil, nor does it require shielding.)
