这是一个关于基于VCSOA的光开关的仿真程序。仿真程序基于传输矩阵法设计的，将整个器件在轴向按折射率的不同分成很多层。计算了在外部抽运（即泵浦，加在放大器上的工作电流）呈现周期性变化时，放大器将输出一系列的光脉冲，即光开关。 ( This is a simulation package for computing the characteristics of the VCSOA when acting as an optical switch, which is designed based on TMM( transfer matrix method). The whole device is splitted into many segments in the axis direction according to different index. When the external pump is a periodic signal, the output of the VCSOA would be a pulse train, which can be used as optical switch. )

- Stone column play important role in infrastructure, improving soft soil. The behaviour of stone column, however, remains far well understood

（注意，之前上传的Fea_Gabor_brodatz有误）该代码为用gabor变换算法提取图像的纹理特征，用matlab编写，可应用于基于纹理的图像检索系统。其中还包含一篇gabor变换相关的文献(The code for the transformation algorithm using gabor texture features extracted using matlab preparation, can be applied to image retrieval system based on texture)

对信号进行内插处理，有16个复信号：1~16Hz；内插I=16 ；内插前采样率50Hz；滤波器265阶 。(Interpolation processing signal 16 multiplexed signals: 1 Hz to 16 Hz interpolated I = 16 before interpolation sampling rate of 50Hz filter 265 order.)
