基于boost电路的双闭环PI控制单相有源功率因数校正仿真模型(Single-phase Active Power Factor Correction Simulation Model of Double Closed-loop PI Control Based on Boost Circuit)

颜色量化算法，在HSV空间将颜色量化为128维(colorhist algorithm，the color is divided 128)

用自相关法求重构相空间的延迟时间的matlab程序(With the autocorrelation method for the reconstruction phase space of the delay time of the matlab program)

基于BOOST斩波电路的MTALAB仿真，仿真结果正确，开关电源设计必备仿真(BOOST chopper MTALAB based simulation, simulation results are correct, switching power supply design must Simulation)

本演示实现了主动轮廓模型由Kass等人提出。 要运行它的图形用户界面 1。基于MATLAB型引导提示。 2。关于“到现有的图形用户界面，点击” 3。选择在与本文件相同的目录snk.fig文件 4。按一下上方的绿色箭头启动图形界面 一旦GUI已经启动，您可以通过使用蛇 1。点击“新形象”，并加载输入图像。提供的样品图像。 2。平滑参数设置“西格玛”或保留其默认值并点击“过滤器”。这将平滑图像。 3。只要你点击“过滤器”，头发会出现交叉，用他们和你左击鼠标，您可以选择在图像上的初始轮廓的位置。会出现一个红色圆圈到处您单击并在多数情况下，你应该单击对象周围的一切你想要的部分。最后一点，必须挑选使用右键单击，以阻止更多的积分为MATLAB的要求。 4。设置各种蛇参数（在能源方面的相对权重的蛇目标函数）或离开它们的默认值，然后按一下他们“迭代”按钮。蛇会出现和移动，因为它收敛到它的低能量状态。(This demo implements the Active Contour Models as proposed by Kass et al. To run it with GUI 1. Type guide on the matlab prompt. 2. Click on "Go to Existing GUI" 3. Select the snk.fig file in the same directory as this file 4. Click the green arrow at the top to launch the GUI Once the GUI has been launched, you can use snakes by 1. Click on "New Image" and load an input image. Samples image are provided. 2. Set the smoothing parameter "sigma" or leave it at its default value and click "Filter". This will smooth the image. 3. As soon as you click "Filter", cross hairs would appear and using them and left click of you mouse you can pick initial contour location on the image. A red circle would appear everywhere you click and in most cases you should click all the way around the object you want to segment. The last point must be picked using a right-click in order to stop matlab for asking for more points. 4. Set the various snake paramete)

说明：  GA遗传算法的入门教程 很是适合初学者,是不错的教材 有源程序(GA genetic algorithm was very introductory tutorial for beginners, is a good source of teaching materials are)

matlab教学从入门到精通 是初学者必备(matlab teaching beginners from entry to the master is essential)

This example demonstrates how to use the backend service in Google-App-Engine. 1. Change name of application in app.yml and firstmodule.yaml to the name of you application 2. Upload the files 3. Open the main page

定步长ODE4、ODE5算法，用法和ode45相似 唯一不同的就是ode45是[t,y]=ode45(), 这个是y=ode4()，因为是定步长的(Fixed-step ODE4, ODE5 algorithms, usage, and the only difference is similar to ode45 ode45 is [t, y] = ode45 (), this is y = ode4 (), because the step length is fixed)

QAM调制软比特解调，能够更准确进行解调。(Soft bit QAM modulation and demodulation, can be more accurately demodulated.)
