说明：  基于灰色预测，指数平滑预测的几个MATLAB程序，对于预测类问题的数学建模，可以说是必备程序。我的导师给我传的。 funesm1,2,3分别为一二三次指数平滑预测程序 fungry为灰色预测程序 funcoef为时间序列预测程序 pudn为广大的编程爱好者提供了一个交流的平台，我在此先谢谢网站的工作人员，我也会努力编出好的程序，一起同大家分享。(Based on Gray predicted that the number of exponential smoothing forecasts MATLAB procedures, issues for the prediction of the mathematical modeling, can be said to be an essential procedure. My mentor gave me spread. funesm1, 2,3 were 123 times procedures fungry exponential smoothing forecast procedures funcoef gray prediction for time series forecasting procedures for pudn programming for the majority of fans provided a platform for exchange, I would like to thank the site staff, I will strive for a good program, to share together.)

说明：  使用matlab处理数理统计中的区间估计的问题(Processing using matlab mathematical statistics in the problem of interval estimation)

光滑比的检验，用于灰色预测模型的建立过程，如果数据达不到要求，就不能用来预测(to exam it whether smooth or not)

ITS A MATLAB CODE FOR CR

以某些特殊函数为基将数据过程或数据系列变换为级数系列以发现它的类似频谱的特征，从而实现数据处理。(In certain special functions as the base data process or data series is converted into the series at a similar spectrum to find that it features, in order to achieve data processing.)

用牛顿拉夫逊法的极坐标形式计算电力系统潮流(Newton Raphson method polar form power flow calculation)

语音信号处理中挺实用的程序，用MATLAB实现LPC谱的分析，对初学者很有用处。(Very useful program in speech signal processing, with MATLAB implementation LPC spectrum analysis, useful for beginners.)
