非常好的导航信号性能评估程序！频谱，码跟踪误差，自相关，均方带宽等！(Very good navigation signal performance evaluation process! Spectrum code tracking error, autocorrelation, mean-square bandwidth!)

说明：  八向链码程序，比较有用，在MATLAB环境下使用(Eight to chain code process, more useful, in the MATLAB environment)

用递推的极大似然法对系统辨识(递推的极大似然法辨识程序)希望通过站长审核(recursive use of the maximum likelihood method of system identification (recursive maximum likelihood method identification procedures) through head of audit)

三种方法实现数字下变频：直接法、bessel插值、多相滤波等(three method of DDC)

多变量频域设计 绘制逆奈奎斯特曲线的函数的改进(multivariate frequence)

说明：  一个matlab的工具包,里面包括一些分类器 例如 KNN KMEAN SVM NETLAB 等等有很多.(a Matlab tool kits, including some inside classifier for example KNN KMEAN SVM NETLAB etc. plenty.)

说明：  基于代理模型的工程设计Exploring and Exploiting a Surrogate(Exploring and Exploiting a Surrogate)

uses partial correlation function and filter to implement an AR model

说明：  利用matab和vc混合编程的简单小例子，学习的同学可以参考一下(Hybrid programming using vc matab and simple small example, students can refer to learning)

这几段程序分别是matlab环境下图像逻辑操作、交换显示图像、矢量数据的显示、交换显示图像(These paragraphs procedures are logical operations matlab environment image, switching display images, vector data display, switching the display image)
