基于神经网络的地震预测程序和研究，只要输入数据就可以了。(Program and research of earthquake prediction based on neural networks, as long as the input data.)

主要用于绘制图像、比如圆柱、矩形、圆、心等，该例子绘制了一颗被包围的红心，用于表达爱意。(Mainly used to draw the image, such as cylindrical, rectangular, round, heart, etc., which are surrounded by examples drawn a red heart for affection.)

说明：  Matlab Simulink仿真程序，主要完成了pv光伏阵列的搭建。(Matlab Simulink simulation program, mainly completed the PV array construction.)

it is for electrical engineering, expecially for power systerm. it is for NR—powerflow.

说明：  稀疏的牛顿法潮流程序，谢谢。请下载使用。(Sparse Newton Flow program, thank you. Please download.)

说明：  课本配套资料 飞思图书：神经网络理论与Matlab7实现 全部为.m格式代码(textbooks information supporting interchangeable books : neural network theory and achieving all of Matlab7. M code format)

matlab中包括各种函数、命令含义、还有simulink模块的(matlab include a variety of functions, commands, meaning simulink module)

基本原理就是首先求解出连续系统微分方程的近似解，然后对系统的Jacobian矩阵进行QR分解，计算Jacobian矩阵特征值的乘积，最后计算出LE和分数维(The basic principle is to first find the approximate solution of differential equations continuous system, then the system will be on the Jacobian matrix QR decomposition product Jacobian matrix computing eigenvalues, and finally calculate the fractal dimension LE)

说明：  一大批产生随机数的经典算法，非常有用，推荐实验中应用(A large number of classic algorithms for generating random numbers, very useful)

说明：  BP神经网络基本算法的matlab实现方式，具体内容需要修改(BP matlab)
