本程序的功能是用牛顿－拉夫逊法进行潮流计算(This program function is to use Newton- rafer Johnson flow calculation method.)

2 gaussian random variable generation and plotting using matlab code

说明：  这是一个图论工具箱，内包含25个图论算法，包括最小路径规划，和旅行商问题。(This is a map of the toolbox, which contains 25 plans of algorithms, including the smallest path planning, and the traveling salesman problem.)

时序差分学习是强化学习的一种重要算法，该代码提供了时序差分学习做路径规划的一个仿真。(Temporal difference learning is an important algorithm for reinforcement learning, which provides a simulation of sequential differential learning for path planning.)

该算法利用BP神经网络描述了一个同心圆的分类算法。特点是可以任意定义多个隐层及隐层内的神经元数目。(the algorithm discribed a category of samecircle.with it you can define any number of buried layer and never cell number of each buried layer.)

QPSK信号在加入白高斯噪声（AWGN）后，用matlab进行仿真，并绘制了误码率图形。( The QPSK signal after joining the white gaussian noise (AWGN), carries on the simulation with matlab, and has drawn up the error rate graph. )

数字图像隐藏技术的仿真，针对一个图片现将其转换为灰白图像，然后将要隐藏的图片加入样本中，加入椒盐噪声攻击，最后将图片还原。(Digital image information hiding technology simulation, for a picture now converted to gray image, will then be hidden image is added to the sample, adding salt and pepper noise attack, finally will restore the picture.)

说明：  计算语音段短时能量的matlab程序，希望对大家能有所帮助。(Calculation of the energy in the short run matlab voice procedures in the hope that we can help.)

matlab与有限元算法书的程序，我改编过其中的算法，可以用其中“hang架算例文件”中我编的例子算，都正确，我算过了(Matlab finite element method and the procedures, which I adapted over the algorithm, which can "hang-count cases document" I count series of examples are correct, I counted the)

能将频带分解为几个不同频率的信号，可以帮助程序员在做小波变换时使用(Band decomposition can be for several different frequency signal，Can help programmers to use when doing wavelet transform)
