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. )

this is implementation steganography using LSB, you must try code. i think

一个三维共形时域有限差分方法，很实用，对于处理三维FDTD算法问题，很有实际价值。(A three-dimensional conformal finite-difference time domain method is very practical.It has practical value to deal with the problem of 3D fdtd algorithm.)

breast cancer dataset，是研究支持向量机，样本选择方法，核方法的一个非常重要的数据集(breast cancer dataset, is to examine the support vector machine, sample selection methods, nuclear methods of a very important data set)
