fisher face recognition and the program is very nice for the face classification.(err)

bp_innerloop.m Inner loop of the backpropagtion learning algorithm. One hidden layer. Uses tanh as the transfer function. Uses the following global variables for input and/or output: Inputs1 - input patterns Desired - desired output patterns LearnRate - learning rate parameter Momentum - momentum parameter DerivIncr - increment to the derivative of the transfer function (Fahlman s trick typical value 0.2) Weights1 - first weight layer (updated by this routine) Weights2 - second weight layer (updated by this routine) deltaW1 - initialize to 0 before first call deltaW2 - initialize to 0 before first call TSS - total sum-squared error (set by this routine) Recurrent state

前推后代潮流计算 把节点按不同类型定义为三类节点，方便计算(Forward offspring flow calculation node according to the different types of definitions for the three types of nodes, to facilitate the calculation)

说明：  运用matlab求矢量x的均值和方差。代码实现简单，运行正确(Using matlab find the mean and variance of the vector x. Code is simple, right)

统计学习基础——数据挖掘、推理与预测。数据挖掘经典教材。(The classical book for data mining. The Elements of Statistical Learning, Data Mining, Inferrence, and Prediction.)

20年来阵列波束形成的发展（延时求和算法、基于波束谱估计的算法、互相关算法、参数法）(Two decades of array signal processing)

本文档很好的阐述了软件开发过程中要注意到的版本控制问题，提出了很好的管理经验，供大家参考(This document set out a very good software development process should be noted that the version control problems, made a very good management experience, for your reference)

建立复杂网络中四个基本网络模型，以及求各种基本属性(struct models for the four basic complex networks and tell us how to resolve the basic proprties)

说明：  四类语音信号的BP神经网络识别： 四个特征信号矩阵合成一个矩阵， 根据BP网络输出找出语音数据属于哪类， 并求出判断正确率(BP neural network to identify four categories of speech signals MATLAB)

说明：  参考维基百科（https://en.wikipedia.org/wiki/Variance-based_sensitivity_analysis）的取样过程以及对应的Estimators。理论性的东西就不进行复述了，这里主要阐述用MATLAB（R2018b）对某个特定函数进行Solo indices敏感性分析的过程。大致可分为四个过程：采样，构建函数，函数输出（将样本带入函数得到输出值），计算Sobol指数（估算一阶影响指数和全局影响指数）(Sobol global sensitivity analysis)
