说明：  大型的光伏电站逆变器，用于相关控制的理论研究与仿真，逻辑性强，详细，很有参考价值(Large-scale photovoltaic power plant inverter for the relevant control theory and simulation, logical, detail, great reference value)

用谱方法计算流体力学一些流动现象的整体稳定性,相控阵天线的方向图（切比雪夫加权），线性调频脉冲压缩的Matlab程序。( Spectral methods of computational fluid dynamics flow of some of the overall stability of the phenomenon, Phased array antenna pattern (Chebyshev weights), LFM pulse compression of the Matlab program.)

computed distribution of the magnetic field Hz within an wvolving 2D dielectric mircopille with initial r=667nm run in COMSOL with Matlab

参数假设检验：对差异进行定量的分析，确定其性质，是随机误差还是系统误差. 为给出两者界限，找一检验统计量T，在H0成立下其分布已知.(Parameter hypothesis test: a quantitative analysis of the differences, to determine its nature, is random error or system error. Is given two boundaries, looking for a test statistic T, its distribution under the establishment of the H0 known.)

很实用的MATLAB SVM KNN算法,适合7.0以上的办版本使用。(very good)

四点定位，声源定位，可连续模拟多个声源进行定位模拟(Four-point positioning, sound source localization, continuous simulation of multiple sound source localization simulation)

求信号的时频熵，对非平稳信号进行emd分解后，求时频熵，得出其故障特征(For the signal s time-frequency entropy, the nonstationary signals are EMD decomposition, and time-frequency entropy, the fault feature)
