说明：  熵权计算算法，客观权重计算方法，避免主观性对权重的影响(Entropy calculation algorithm, the objective weighting method, to avoid the subjectivity of the impact of weight)

本人自己做的功率谱估计的课程作业，利用matlab实现古典和现代功率谱估计，有间接法，burg法，music法。完全一步一步实现的，希望对大家有帮助(Course work, I do own the power spectrum estimation using matlab classical and modern power spectrum estimation, the indirect method, burg, law, music law. Full step by step, we hope to)

OFDM-LFM雷达的设计，MATLAB仿真，非常全面的程序(OFDM-LFM radar design, MATLAB simulation, a very comprehensive procedure)

非线性加速度法计算单自由度体系地震时程反应,刚度矩阵，地震反应(Linear acceleration method to calculate the single degree of freedom system earthquake history response, stiffness matrix, seismic response)

k-means聚类算法的matlab代码 截图的 想用还是自己手打吧(k-means clustering algorithm matlab code screenshot or their own hands to fight it.)

matlab中同步电机在dq轴系下的建模，转子绕组短路定子绕组突然加对称电压，有阻尼绕组，自己用S函数编的，很好用的哦，适用于初学(matlab modeling of the synchronous motor in dq shaft under the rotor winding short-circuit the stator winding suddenly and symmetrical voltage damper winding, S function series, very good used, suitable for beginners)

利用Matlab软件编写的轨道不平顺数据分析程序能够对轨检车测得的不平顺数据进行处理,得到功率谱密度分布函数.轨道不平顺分析程序包括轨道不平顺数据预处理、轨道不平顺谱分布函数计算以及根据实测的车体振动加速度,对轨道不平顺与车体振动加速度进行相干分析、提出对行车运行有不利影响的不平顺波长范围等.研究结果表明:车辆的动力特性与轨道不平顺有密切关系.高低不平顺对车体垂向振动影响显著,轨向不平顺对车体水平振动影响显著,水平不平顺对列车垂向、横向振动均有显著影响.(Matlab software written track irregularity data analysis program able to track inspection car irregularity measured data are processed to obtain the power spectral density function. Track Irregularities track irregularity analysis procedures including data preprocessing, track irregularity spectrum distribution function calculations, and based on the measured vibration acceleration of the vehicle, with the body of track irregularity acceleration coherent analysis, have an adverse impact on traffic running irregularity wavelength range, etc. the results show that: the dynamic characteristics of the vehicle and the track irregularity closely related. rough along the vertical vibration of the vehicle significantly, rail irregularity vibration to levels significantly affect the body, the level of irregularity to train the vertical and horizontal vibration significantly affected.)
