matlab最全纹理特征代码，灰度共生矩阵软件自带，就不传了。里面有tamura六个参数，灰度梯度共生矩阵的纹理特征，还有熵。(matlab the best texture feature code, the GLCM software comes not passed. Tamura six parameters, the shades of gray co-occurrence matrix texture features, as well as entropy.)

C++ SGP4 Satellite Library

说明：  遗传算法反演程序源代码，主要反演瞬变电磁数据(Code for GA)

The following is an example of how Microsoft Solver Foundation can be used to solve a constraint satisfaction problem (CSP) like generating a typical Sudoku problem. Sudoku http://www.codeproject.com/Articles/419389/Sudoku-using-Microsoft-solver-foundation In this article I do not attempt to explain everything there is to know about constraint satisfaction problems, but I will go over the concepts in the hope that even if you have never heard of CSP you will still get the idea.

《Optimal State Estimation - Kalman, H Infinity, and Nonlinear Approaches》 一书的配套源码，包括了Kalman Filter、Hinf Filter、Particle Filter等的Matlab源码(《Optimal State Estimation- Kalman, H Infinity, and Nonlinear Approaches》source code，including Matlab code of Kalman Filter、Hinf Filter、Particle Filter.)

1、根据所给的中国版图数据 绘制显示基于北京54坐标系的经纬度数据 编写兰勃特投影转换程序，转换上述数据，并显示 编写墨卡托投影转换程序，转换上述数据，并显示 同时，要绘制相对应的经纬网格，网格间距5度 2、根据所给的世界版图数据 绘制显示基于WGS84坐标系的经纬度数据 编写墨卡托投影转换程序，转换上述数据，并显示 计算北京(116.4，39.8)到巴黎(2.2, 48.52)的大圆轨迹，并显示 同时，要绘制相对应的经纬网格，网格间距5度(1, according to the Chinese territory given display data drawn based on latitude and longitude data write Beijing 54 coordinate system Lambert projection conversion process, the conversion of the data, and displays the write Mercator projection conversion process, the conversion of the data, and display the same time, Draw the corresponding latitude and longitude grid, the grid spacing of 5 degrees 2, according to the world map rendering display data written to the Mercator projection based on latitude and longitude data conversion program WGS84 coordinate system, the conversion of the data, and displays the calculation Beijing (116.4, 39.8) to Paris (2.2, 48.52) the great circle track and display the same time, to draw the corresponding latitude and longitude grid, the grid spacing of 5 degrees)

一些简单的UDF文件，实现流场中梯度和某一点压力的检测提取(Some UDF profiles)

用C语言实现解决约瑟夫问题的一种方法，也许会对他人有启示。(C language implementation with a way to solve the problem, Joseph, and perhaps others, would be revealing.)

说明：  各种滤波器，包括高通、低通、带通等滤波器，可用，直接输入数值即可，可直接使用，没有bug(bandpass filter,Band pass filter, available, direct input value, can be used directly, no bug)
