蓝牙定位的DEMO,安卓要求4.4,如果没有4.4就不行哦(Bluetooth positioning DEMO, Andrews requires 4.4, 4.4 will not work if not oh)

超宽带测距中，选目的节点和参考节点。输入节点数量为N和希望的参考节点数量为K，函数返回一个表示目的的节点的整数Nx和一个K维的包括了参考节点ID号的矢量Ref。(Ultra-Wideband Ranging choose destination node and reference nodes. The number of input nodes for N and hope the number of reference node K, the purpose of function that returns a whole number of nodes Nx and including a K-dimensional reference vector of node ID No. Ref.)

This is a sample code in Matlab designed to solve a finite element modeling problem on a rectangular platform.

ESPRINT谱估计，计算DOA，可以与capone进行对比。(ESPRINT spectrum estimation calculates DOA, with capone comparison.)

压缩感知程序，利用CS对一维信号进行完美重构，适合稀疏信号(Compressed sensing applications, the use of CS for one-dimensional signal is perfect reconstruction, suitable for sparse signal)

Demo macro to extract frames and get frame means from an avi movie and save individual frames to separate image files. Also computes the mean gray value of the color channels.

较为详细地介绍了单同步坐标系软件锁相环，采用了单一的同步坐标系锁相控制结构，一般适用于电网电压平衡时的相位，频率及幅值的检测，以及用于多种控制结构中（下垂控制，PQ控制，双闭环控制）。(A more detailed description of the principle of a single coordinate system PLL synchronization and setting PI controller parameters. SPLL with a single synchronous coordinate system lock control structure, generally applicable to the detection phase, frequency and amplitude of the grid voltage at equilibrium, as well as for a variety of control structures (droop control, PQ control, dual loop control).)
