simulink的经典用法,偶然在其他地方看到的,和大家共享(simulink classic usage, occasionally, in other places to see, and everyone shared)

异步电机的Vf控制策略simulink仿真研究，效果良好，可以修改参数(Vf control strategy of induction motor simulink simulation results were very good, you can modify the parameters)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

DAta Encryption standard implemented IN MATLAB

使用最大期望算法可以在概率模型中寻找参数最大似然估计。(Using the maximum expected algorithm can seek parameters of maximum likelihood estimation in the probabilistic model)

Three phase high frequency isolated DC-DC converter (published in ELSEVIER)is simulated under symmetrical open loop control. It provides Low voltage conversion ratio, isolation, good regulation with fast dynamic response.

This matlab code describes Perturbation and observation algorithm for calculation of maximum power point of a PV module. It is a basic example.
