卫星在WGS84坐标系下的坐标转换为站心坐标(WGS84 coordinates to topocentric coordinates)

马可夫决策过程，适合最优策略选择，可以作为一个工具包调用(The Markoff decision process, suitable for the optimal strategy selection, can be called as a toolkit)

一个可以进行图片矫正的例子程序，可以很好的实现图片倾斜矫正，仅供参考(A picture can be corrected example program, you can achieve a good image tilt correction, for reference only)

C source of Multistage Vector Quantization

说明：  此Matlab代码实现了Drude-Lorentz和Debye-Lorentz算法(LD模型)，用于计算金属的介电常数。当然Drude-Lorentz方法也可以用来计算纯水的。(This Matlab code implements the Drude-Lorentz and Debye-Lorentz algorithm (LD model), used to calculate the dielectric constant of metal. Of course, Drude-Lorentz method can also be used to calculate the pure water.)

说明：  基于lsb的音频水印程序，能正确运行，希望有用(Audio watermarking program based on LSB)
