用Matlab编程编程是实现的扫雷游戏，不足之处请指教(Programming with Matlab programming is to achieve the minesweeper game, shortcomings Please advise)

本文讲述锁相环的工作原理，锁相环路实际上是一个相差自动调节系统。(This article describes the working principle of PLL, PLL is actually a difference between the automatic adjustment system.)

很好用的matlab源代码，值得作为参考。源代码可以直接拿来应用。(can run smooth)

主成分分析 求标准化后的协差矩阵,再求特征根和特征向量(main analysis)

说明：  行向量绘图，在matlab中对于含有大量的数据，单独在一张静态的图上是显示效果是很不理想的，这个程序实现了在matlab中以示波器的形式动态的显示器波形图(Row vector graphics in matlab in containing a large amount of data, alone in a static chart is to show the effect is not ideal, the realization of this procedure in matlab in the form of oscilloscope waveform display dynamic)

AR过程的线性建模与功率谱估计 自相关值和Yule-Walker法(自相关法) 协方差法； Burg方法； 修正协方差法。(The linear AR process modeling and power spectrum estimation of autocorrelation and Yule-Walker method (autocorrelation) covariance method Burg method modified covariance method.)

The program generates Gold Codes.
