本程序为地球直角坐标转球面做的程序，本程序考虑到了不同的地球模型，采用了对应于不同模型的参数(This procedure turn spherical Earth Cartesian coordinate the program, the program taking into account the different Earth model using the parameters corresponding to the different models)

双馈风机（DFIG）在matlab/simulink中的dq模型(the dq-model of DFIG in matlab/simulink)

很全的matlab 命令集，很不错，共享下。(Very wide of the matlab command set, it is good to share.)

matlab 图像处理源代码，比较全，有多个matlab程序(matlab image processing source code, compare the whole, there are several matlab programs)

BP算法用MATLAB语言的实现方法 文献内系统讲述了BP网络的定义 算法 建模和应用的知识，方便大家学习使用(BP Algorithm Implementation with MATLAB language)

GNSS接收机主程序Matlab源代码 包括：捕获、跟踪、解算定位(GNSS Matalab Receiver)

fft的c++语言实现，改自matlab的相关程序(fft c++)

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)
