实现锁相环的基本功能，主要是用matlab实现相关的功能(PLL to achieve the basic functions, mainly related functions using matlab)

该程序是QR解矩阵特征值的，matlab程序(The program is the solution matrix eigenvalue QR)

基于matlab的电力系统配电网IEEE9节点潮流计算，希望对大家有帮助(Matlab-based power system IEEE54 node flow calculation, we hope to help)

功能描述见readme文档 包括GPS的捕获算法和数据(Function described in readme file including GPS algorithms and data capture)

模拟2个独立窄带信号分别以20°，60°的方向入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵元数为10，快拍数为200，信噪比为20dB，阵元间距分别为 tambada/6 tambada/2、tambada。(Simulate two independent narrowband signals in the direction of 20 °, 60 ° of the incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the array element number 10, the number of snapshots for 200, SNR is 20dB, respectively array element spacing  tambada/6 tambada/2, tambada.)

该程序用于计算n根平行导线间的串扰,程序结构及说明见程序内。源可以是单频的或脉冲的（这里给出的是频域的）。频率、波形、线长、电源及负载阻抗均可在用MATLAB编写的语句中方便地修改。但必须输入导线系统每单位长度的电感、电容矩阵。(The procedure used to calculate n root of crosstalk between parallel wires, program structure and description of process. Source can be single frequency or pulse (here is given by the frequency domain). Frequency, waveform, the line is long, power and load impedance can be found in the use of MATLAB statements prepared easily modified. However, the system must enter a wire per unit length inductance, capacitance matrix.)

序列进行离散傅里叶级数变换，画出相位图，频谱图。改变序列长度，然后重复上述过程(Sequence of discrete Fourier series transform, draw the phase diagram, spectrogram. Change the length of the sequence, and then repeat the process)

用Matlab实现自适应增量调制及线性增量调制，并进行对比，有详细的注释及编程说明、结果分析(Matlab implementation using adaptive delta modulation and linear delta modulation, and contrast, there is a detailed description of the Notes and programming, the results of analysis)

基于粒子滤波实现的目标被动跟踪，适合初学者学习。(Goal-based particle filter tracking, suitable for beginners to learn.)

这是一种改进的粒子群优化算法，通过简单的测试函数验证(This is an improved particle swarm optimization, through a simple test function verification)
