四个人位于正方形的四个顶点，相互对准下一个人追逐，形成四条螺旋线，螺旋线的matlab仿真代码(4 person ，each one is running after another. the file is the Word for paiting the picture of the contrail they go )

matlab高级应用教程，涉及到插值方法、高斯积分、边值问题、动力学相应分析、非线性积分、弯曲梁结构计算等等(matlab tutorial for advanced applications involving the interpolation method, the Gaussian integral, boundary value problem, the corresponding dynamic analysis, nonlinear integral, bending beam structure calculation, etc.)

说明：  最大功率跟踪，实现光伏发电最大功率跟踪，输出完美波形(Maximum power tracking, realize the maximum power tracking of photovoltaic power generation,output perfect waveform)

说明：  考虑环境因素的多目标优化方法，采用传统的遗传算法，同时考虑环境和经济性，考虑帕累托策略。(The multi-objective optimization method considering the environmental factors, using the traditional genetic algorithm, while considering the environment and economy, considering the Pareto strategy.)

matlab官网的时钟程序，请大家欣赏，资源共享(the clock programme used the matlab,it is wonderful ,thanks)

自己做的SPWM逆变器的simulink仿真(Do their own SPWM inverter simulink simulation)

SIMULINK仿真实现BPSK在莱斯衰落+AWGN信道中的调制与解调，并分析了误码率和星座图等等参数。(SIMULINK simulation of BPSK in Rician Fading realize+ AWGN channel modulation and demodulation, and analyzes the bit error rate and constellation parameters and so on.)

在计算机上产生一组实验数据，首先产生一段零均值白噪声数据u（n）,令功率为 ，让u(n)通过一个三阶FIR： 得到y(n). .y(n)上加三个实正弦信号f1’=0.1,f2’=0.25,f3’=0.26调整 和正弦信号幅度信噪比大致为10dB,50dB,50dB. (1) 令N=256,描绘xn波形； (2)得出真实功率谱密度 . (3) 利用此实验数据Pisarenko谐波分解法估计该实验数据的正弦频率及幅度。 (On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)

These codes are very useful in the simulation of HAP
