利用類神經網路對Schwefel22測試函數建立模型，為此Schwefel22函數設立4個變數，模擬資料100筆，測試資料50筆，並將上述資料以倒傳遞類神經網路MATLAB2013a軟體，利用其具有學習及記憶能力加以訓練及測試(The use of neural network modeling of Schwefel22 test functions, established for this purpose Schwefel22 function four variables, simulation data 100 pen, 50 pen test data, and these data to back-propagation neural network MATLAB2013a software, the use of which has learning and the ability to be trained and tested memory)

述是经典MUSIC算法的基本原理，许多限制是可以放宽或取消的。首先，关于均匀线阵的限制不是必须的，实际中可采用几乎是任意形状的阵列形式，只要满足在个独立信号源的条件下，矩阵具有个线性无关的列就可以了。其次，天线阵元在观测平面内无方向性这一点也不是必要的，而且还可以考虑三维空间的DOA估计问题，即不仅估计信号的方位角，还要估计它的俯仰角，当然MUSIC算法还用于频率、方位和俯仰的联合估计。(Above is the basic principle of the classical MUSIC algorithm, a number of restrictions can be relaxed or canceled. First, restrictions on ULA is not necessary, the actual form of an array can be almost any shape, as long as the signal source in the independent condition matrix has linearly independent columns on it. Second, the antenna elements in a plane non-directional observation it is not necessary, but could also be considered DOA estimation of three-dimensional space, that is not only estimated azimuth signals, but also to estimate its pitch angle, of course, also MUSIC algorithm joint estimation for the frequency, the azimuth and elevation.)

实现对离网运行的孤岛微电网的可靠性评估，用的是解析法，能够很好的评估孤岛的可靠性。(Realize the off-grid micro-run island grid reliability evaluation using analytical method, can be a good assessment of the reliability of the island.)

首先在m脚本文件canshuo.m中输入节点个数和路径权重，在命令窗口中输入canshu，用s=12,e=10的格式输入要求的起止点，再输入main即可得到两点之间的路径和长度。(M script file canshuo.m first enter the node number and the right path lies in the command window enter canshu, with s = 12, e = 10 The format of the input requirements of the start and end points, and then enter the main between two points can be obtained path and length.)
