关于感知机的一个神经网络例子，适合初学者 可以下来看看(On a neural network perceptron example, suitable for beginners can be down to see)

说明：  络检波法，也可以用同步解调法，现在我们来使用同步解调法，即将已调信号和一个与载波信号同频率的信号相乘，在通过一个理想低通滤波器就可以得到原始信号(Envelope detection method, you can also use synchronous demodulation method, and now we use synchronous demodulation method, is about modulated signal and a signal is multiplied with the same frequency of the carrier signal, through an ideal low-pass filter can get the original signal)

黄金分割法，用于一维线性优化，输入相应目标函数，可得最优变量(Golden method for one-dimensional linear optimization, enter the appropriate objective function, we can get the optimal variable)

本程序是一个数据分类的程序，首先使用KL变换对数据进行降维和去噪，然后用BP神经网络对预处理过后的数据进行分类，并且留有部分的测试集(This program is a data classification program, the first to use KL transform data dimensionality reduction and de-noising, then BP neural network to classify the data after preprocessing, and left part of the test set)

说明：  IEEE33节点的潮流计算程序，使用了前推回代方法。(IEEE33 node power flow calculation program)
