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：  AR参数模型各种算法比较以及matlab实现(AR model parameters as well as a variety of algorithms to achieve matlab)

说明：  很通用的牛顿法潮流计算，收敛性好，结果精确,也是其他潮流计算的基础(power flow of newton)

fuzzy applied local statistic filter

PPM编码器的测试文件，可以测试PPM编码是否正确(PPM encoder test file, you can test whether the correct PPM encoding)

加入载波相位偏差，用最大似然估计和错误估计估计相位误差，并进行比较。(Add carrier phase deviation, using maximum likelihood estimation and errors estimated phase error is estimated and compared.)

Matlab各编程应用实例，并包含正交函数、曲线拟合、回归分析等。(Application of the Matlab programming, and includes orthogonal function, curve fitting, regression analysis.)

三乘四二维数组 求所有元素中最大值，这个程序很简单的，大家看看就好(Three in four two-dimensional array for all elements in the maximum)

计算序列的自相关函数,绘制信号xn的自功率谱幅频曲线,绘制信号yn的自功率谱幅频曲线,计算互谱函数(Calculating the autocorrelation function of the sequence, drawn from the power spectrum of the signal xn amplitude-frequency curve, drawn from the power spectrum of the amplitude-frequency curve signal yn calculated cross-spectral function)
