基于光伏模块直流物理模型，在matlab 仿真环境下，开发了光伏阵列通用仿真模型。利用该 模型，可以模拟任意太阳辐射强度、环境温度、光伏模块参数、光伏阵列串并联方式组合下的光伏阵 列I-V 特性。此外，该模型还融合了光伏阵列的最大功率跟踪（MPPT）功能，可以用于光伏发电系统 和风光复合发电系统的动态仿真。(A Versatile simulation model for photovoltaic array is developed based on the DC physical model of photovoltaic module under Matlab environment. By the model，the I-V characteristics of photovoltaic array with different combinations can be simulated at any corresponding insolation level, ambient temperature and parameters of the photovoltaic module. In addition to that, the model includes the function of Maximum Power Point Tracking(MPPT) . It can be used in the dynamic simulation of photovoltaic systems and wind-solar hybrid systems.)

MeanShift运动目标跟踪 matlab程序 思路： 1.截取跟踪目标矩阵rect 2.求取跟踪目标的加权直方图hist1 3.读取视频序列中的一帧， 先随机取一块与rect等大的矩形，计算加权直方图hist2。 4.计算两者比重函数，如果后者差距过大， 更新新的矩阵中心Y，进行迭代（MeanShift是一种变步长可以迅速接近概率密度峰值的方法），直至一定条件后停止。 (MeanShift moving target tracking matlab program ideas: 1. Interception target tracking matrix rect 2. Strike target tracking weighted histogram hist1 3. Reading of a video sequence, first randomly selected one with such a large rectangle rect, calculate the weighted Histogram hist2. 4 Calculate the proportion of both functions, if the latter gap is too large, updated new matrix center Y, iterative (MeanShift is a variable step size can rapidly approaching the peak of the probability density method), until certain conditions stop.)
