说明：  seir模型模拟传染病 人在康复以后产生了抗体就不会再得病。不同于SIS模型，我们在模型中引入康复者(The Recovered)，用 [公式] 表示，并满足总人数 [公式] 。这个时候就是SIR模型。一旦变为康复者，就不会再传染，即在概率传递过程中，一旦变为康复者，就没有概率再次转移为感染者或者易感者。我们假设感染者变为康复者的概率为我们来看下SIR模型的微分方程(SEIR model simulating infectious diseases)

Function uses Standard Hough Transform to detect circles in a binary image. According to the Hough Transform for circles, each pixel in image space corresponds to a circle in Hough space and vise versa. upper left corner of image is the origin of coordinate system.

MATLAB 软件是当今控制系统的设计与仿真中重要的工具软件。该软件仿真方便， 结果直观、准确。本文以单相桥式全波可控整流电路及三相桥式全波可控整流电路为例，叙 述了利用 MATLAB/SIMULINK对整流电路进行建模仿真的方法，并给出了仿真结果波形。 通过对仿真结果分析就可以将系统结构进行改进或将有关参数进行修改使系统达到要求的 结果和性能，这样就可以极大地加快系统的分析或设计过程。 (MATLAB software is the current control system design and simulation of the important tools. The software simulation convenience, the results of direct and accurate. In this paper, single-phase full wave controlled rectifier bridge and three-phase full wave controlled rectifier bridge, for example, describes the use of MATLAB/SIMULINK model of the rectifier circuit simulation method, and gives the simulation results waveform. Through the simulation results of the system structure can improve or modify the relevant parameters of the system to achieve the required results and performance, so that you can greatly speed up the system analysis or design process.)
