在matlab中实现对矩阵数组的灰色预测，预测出后三年的数据(In matlab to achieve an array of matrix grey prediction, predict three years after data )

考察一个在热循环中的表面贴片电阻。一般情况下，连接贴片电阻与电极的焊点是其中最薄弱的环节，它通常对温度和时间表现出较强的非线性。为了确保结构的完整性，基于蠕变应变和耗散能进行了疲劳分析。(This case study of a surface patch resistance in a thermal cycle. In general, the solder joint is the weakest link, which usually shows strong nonlinearity in temperature and time. In order to ensure the integrity of the structure, the fatigue analysis is carried out based on the creep strain and dissipation energy.)

在这个更新的代码，新功能，包括colorbar，samesize包括向量plottting... ％更新版本$日期：5月18日，2011年由梁枯盎斯蒂文斯技术学院 ％更新1：更改int8到Int16的colormap的是，当电流超过64个大，这将导致错误 ％更新2：加入 samesize 为使所有的向量samesize ％更新3：添加colorbar相应的开方的幅度（ü^2+ V键^ 2） ％更新4：错误修复，当你为h = quiverc，这是行不通的。 ------------------------------------------------- ----------- (In this updated code,new features including colorbar, samesize vectors plottting are included Updated version $Date: May 18th,2011 by Liang Kuang at Stevens Institute of Tech Update 1: Change int8 to int16 when current colormap is bigger than 64,which will cause error Update 2: Added samesize for making all the vectors the samesize Update 3: Add colorbar corresponding the the magnitude of sqrt(u^2+v^2) Update 4: bug fixed,when you do h=quiverc, it doesn t work. ------------------------------------------------------------)
