matlab程序，用于计算振动测试中歪度与峭度的函数。(matlab program, used to calculate the vibration test skewness and kurtosis of the function.)

说明：  利用Dijkstra算法来求网络图的最短路径，找到从起点P1到终点Pn的最短路径，由于上述算法使用了连接线中点的条件，不是整个规划空间的最优路径，然后利用遗传算法对找到的最短路径各个路径点Pi (i=1,2,…n)调整，让各路径点在相应障碍物端点连线上滑动(Use Dijkstra algorithm to find the shortest path network diagram to find the starting point P1 to the end of Pn from the shortest path algorithm is used as the midpoint of the condition of cable, not the entire optimal path planning of space, and then use genetic algorithm to find shortest path of each path points Pi (i = 1,2, ... n) adjusted to the path of obstacles in the corresponding endpoint connection point slide)

说明：  以单相光伏发电并网系统为研究对象，基于Matlab/Simulink平台，进行了光伏电池的建模，MPPT模型的搭建，并实现了系统的并网。(Taking the single-phase photovoltaic power grid system as the research object, based on MATLAB / Simulink platform, the photovoltaic cell modeling and MPPT model are built, and the grid connection of the system is realized.)

小波工程主要包括一两部分：一、连续小波分析的应用，二、离散小波分析的应用。下面分两个部分分别说明这两个程序的分析结果： 一、连续小波分析： 所用信号为自己构造的三角波和正弦波叠加的信号：s=(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3+1*cos(n/2)*10。其中第一项(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2为一周期为100的锯齿波，第二项-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3为一周期为34的锯波，第三项为一周期为4*pi正(余)弦波。另外叠加了一幅度为5的噪音信号。 程序包包含程序与说明文档。(Wavelet works mainly consists of two parts: first, the application of continuous wavelet analysis, II, Discrete Wavelet Analysis.)
