可以用来求复合半导体能带随着偏压的变化情况，可以考虑到interface charges(Can be used for compound semiconductor energy band changes with the bias, you can take into account the interface charges)

it contain drive of induction motor without loss

这是我自己调试好了的彩色图像增强的，绝对可以使用，非常好。(This is my own and tested the color image enhancement, absolutely you can use, very good.)

系统的结构参数和负荷情况都已给定时，调节可利用的控制变量(如发电机输出功率、可调变压器抽头等)来找到能满足所有运行约束条件的，并使系统的某一性能指标(如发电成本或网络损耗)达到最优值下的潮流分布。(Optimal power flow(OPF) is a fundamental tool in power system planning and operation.)

matlab中关于工程数学的应用例程，适合工科学生，针对性强(the common use of matlab to engineering problems)

Generate a random sample of size n a finite mixture estimate of the Old Faithful Geyser data

这个小程序包含结果和程序 可以作为电力系统分析实验报告的节点导纳矩阵的源程序(This little program contains the results and procedures can be used as power system analysis experiments reported node admittance matrix of the source)

说明：  kalman滤波，扩展的kalman滤波（EKF），unscented Kalman filter（UKF），基于EKF和UKF混合模型的IMM实现，以及配套的Rauch-Tung-Striebel和two-filter平滑工具，一个很好用的框架(kalman filtering, extended kalman filter (EKF), unscented Kalman filter (UKF), based on the EKF and UKF realize mixed-model IMM as well as ancillary Rauch-Tung-Striebel and two-filter smoothing tool, a very good framework to use)

说明：  主动频率偏移法，是用来检测孤岛效应的。采用S函数描述(Active frequency shift method is used to detect island effect. Function described by S)
