KNN3

简明的matlab 实用程序集合；可以快速地掌握这一工具进行实际应用(concise Matlab practical procedures set; Quickly grasp of the tools for practical application)

可用于拟合化学分析中的一元线性回归并绘制残差图，找出可疑数据，对化学分析工作者很有用！(Caculated the linear degree and residues of all values you got.Very important for the chemical engineers and scientists.)

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. )
