Floyd最短路算法的MATLAB程序，可以求解最短路问题，比如旅行商问题，(The most short circuit algorithm Floyd MATLAB procedures, can solve the most short circuit problems, such as traveling salesman problem, )

宽带信号的空间谱估计以及信噪比等对信号估计的影响，才用聚焦矩阵的方法，采用的聚焦矩阵不同，性能也不同，这里是RSS算法(Spatial spectrum estimation of wideband signals and SNR of the estimated impact on the signal only with the focusing matrix method, using the focusing matrix of different, performance is different, here is the RSS algorithm)

位置指令为幅值为1.0的阶跃信号，r（k）=1.0。网络结构为1-4-1，高斯函数的参数值取Cj=[-2 -1 1 2]T ，B=[0.5 0.5 0.5 0.5]T 。 网络权值学习参数为η=0.30，α=0.05 。PID控制各参数的初RBF网络控制，被控对象为G（s）= 取采样时间为1ms，采用Z变换进行离散化，离散化后的被控对象为 y(k)=-den(2)*y（k-1）-den(3)*y(k-2)+num(2)*u(k-1)+num(3)*u(k-2) 始值为，kp=20， kd=0.3， ki=0.1。 (Position command for the step signal amplitude of 1.0, r (k) = 1.0. The network structure is 1-4-1, the Gaussian function parameters taken Cj = [-2-1 1 2] T, B = [0.5 0.5 0.5 0.5] T. Weight learning parameter η = 0.30, α = 0.05. PID control parameters at the beginning of each RBF network control, the controlled object is G (s) = take the sampling time is 1ms, using the Z transform discrete, discretized controlled object is y (k) =-den (2)* y (k-1)-den (3)* y (k-2)+num (2)* u (k-1)+num (3)* u (k-2) initial value, kp = 20, kd = 0.3, ki = 0.1.)

随机权神经网络预测光伏电池的光功率的matlab仿真源代码(A random vector functional link network (RVFLN)It is proved that the RVFLN not only trains much faster with good generalization performance, but also overcomes some pos- sible fl aws (such as the low convergence rate and the local minimum) of the BP algorithm. But poor quality RVFLN is usually obtained whenever the training data are corrupted with outliers.)

分别列出BP网络与som网络的代码，通过运行后可以看出同一种问题在不同网络下的处理差别。(A breakdown of BP network and som network code, by running after the same kind of problem can be seen in the different networks of processing differences.)

关于无功补偿的matlab优化程序，节点较多，可自己改动(Reactive power compensation on the matlab optimization procedures, more nodes can change their own)
