主成分分析是把原来多个变量划为少数几个综合指标的一种统计分析方法。 从数学角度来看，这是一种降维处理技术。(Principal component analysis (PCA) is a statistical analysis method that divides a number of variables into a few comprehensive indexes.From a mathematical point of view, this is a kind of dimensionality reduction technology.)

说明：  可实现自动分析，偏最小而成分析，结果可得相关性和RMSEC值(Automatic analysis can be realized, and analysis based on minimum)

matlab 信号采样，补0采样并还原信号(matlab signal sampling, sampling up and restore the signal 0)

Variable declarations in eval() must introduce delete-able vars.

说明：  用平面波展开法计算二维二组元圆柱散射体型声子晶体能带结构的matlab代码。(This matlab code uses PWE to calculate the band structure of 2-D phononic crystal with cylinder scatterer.)

利用matlab控制3维仿真软件sonnet的工具箱，里面包含了详细的试用说明PDF，还有一个微带天线的例子，使得对天线的设计变得简单。(Using matlab to control 3-D simulation software sonnet Toolbox, which contains a detailed description of the trial PDF, there is a microstrip antenna example, makes the simple antenna design.)

《精通matlab GUI设计》可视化编程宝典丛书，书后例程，全书各章所有例程(" Mastering matlab GUI design" Visual Programming Books Collection, the book routines, all routines book chapters)

人工地震波生成程序 可根据输入的设计谱，来生成人工地震波，为matlab程序，应用方便(Artificial seismic waves generated program according to the design of the input spectrum afterlife waves adult site, matlab program, easy application)
