最新的张量分析工具箱，版本2.6,可进行高阶奇异值分解(HOSVD).(Tensor Toolbox (Sandia National Labs) Version 2.6 06-FEB-2015 Tensor Toolbox for dense, sparse, and decomposed n-way arrays)

matlab中使用S函数写的一个PID控制器，并且在simulink中调用，将之与使用simulink模块搭建的PI控制器对比，压缩包中MyPID和PI_Controller是用S函数写的控制器(A matlab source file and simulink simulation. Use S function to generate a PID controller. The controller is applied in the matlab simulink file.)

用matlab仿真的hough变换，希望能与大家共享(Using the hough transform matlab simulation, hoping to share with everyone)

IEC协会推荐的电压波动和闪变的MATLAB计算模型，并含IEC标准（这个标准很难找到免费的）(IEC Association recommended voltage fluctuations and flicker MATLAB computing model, and with the IEC standard (this standard is difficult to find for free))

Hybrid PV-wind generation shows higher availability as compared to PV or wind alone. For rural electrifications, researches are focused on hybrid power system which provides sustainable power. The variable voltage and frequency of the self excited induction generator (SEIG) is rectified through Vienna rectifier (three switches) to the required D.C voltage level and fed to common D.C bus. The variable output voltage of PV module is controlled by DC/DC converter using proposed fuzzy logic controller and fed to common D.C bus. The DC bus collects the total power from the wind and photovoltaic system and used to charge the battery as well as to supply the A.C loads through inverter. A dynamic mathematical model and MATLAB simulations for the entire scheme is presented. Results from the simulations and experimental tests bring out the suitability of the proposed hybrid scheme in remote areas.
