Boost converter used in power electronics is used to boost the output voltage

说明：  程序利用图像处理的一般办法，使用MATLAB将图像中的椭圆提取(Procedures using the general approach of image processing, using MATLAB to extract the image of the ellipse)

Grid-connected photovoltaic (PV) inverters employ an islanding-detection functionality in order to determine the status of the electrical grid. In fact, the inverter must be stopped once the islanding operating mode is detected according to standards and grid-code limits. Diverse islanding-detection algorithms have been proposed in literature to cope with this safety requirement.

cc方法是实现相空间重构时用来计算重构维数和时间延迟的方法，我在这里只是试一试(ccmethod medisine and time delay we implement the program，the word is too leate to upload,so i have to add something to it.i can not do well in english.,)

说明：  矩阵QR分解实例，使用Givens和Householder两种方法(QR decomposition, using Givens and Househoulder method)

卷积编码器g1=111,g2=101 x为输入的待译码序列 x=[1,0,1,0,0,1,0,0,0,1,0,1,1,1] x=[1,1,0,1,0,1,1,0,0,1] x=[1,1,1,0,0,0,1,0,1,1] a=size(x) 输入序列的长度 s=a(2)/2 译码后的m序列长度为x的一半 m=zeros(1,s) 最终结果存放 ma=zeros(1,s+1) 存放Fa路径的 mb=zeros(1,s+1) 存放Fb路径的 mc=zeros(1,s+1) 存放Fc路径的 md=zeros(1,s+1) 存放Fd路径的(viterbi decoder)

说明：  卡尔曼滤波算法功能实现，常见的数据处理方法(Solve the problem of noise error)

在洞穴深处，精灵王子不小心触动了洞穴内暗藏的机关，整个洞穴将很快塌陷，精灵王子必 须尽快逃离洞穴。精灵王子的跑步速度为17m/s，以这样的速度可能是无法逃出洞穴的。庆幸的是精灵王子拥有闪烁法术，可在1s内移动60m，不过每次使用闪烁 法术都会消耗魔法值10点。精灵王子的魔法值恢复的速度为4点/s，只有处在原地休息状态时才能恢复。现在已知精灵王子的魔法初值M，他所在洞穴中的位置与 洞穴出口之间的距离S，距离洞穴塌陷的时间T。你的任务是写一个程序帮助精灵王子计算如何在最短的时间内逃离洞穴。(In the depths of the cave, the elven prince accidentally touched a hidden cave organ, the entire cave will soon collapse, elf prince will Must escape from the cave as quickly as possible. Running speed elven prince of 17m/s, at this rate may be unable to escape the cave. Fortunately elven prince has flashes of magic, can move within 60m 1s, but each use flashing Spell will consume mana 10:00. Elf Prince mana recovery speed of 4:00/s, to resume only in situ resting state. Now the magic elf prince known initial value M, the location of the cave where he and Distance between S cave exit from the cave to collapse time T. Your task is to write a program to help calculate how elven prince fled the cave in the shortest possible time)
