代码说明:

液体分子不停地做无规则的运动,不断地随机撞击悬浮微粒。悬浮的微粒足够小时,受到的来自各个方向的液体分子的撞击作用是不平衡的。在某一瞬间,微粒在另一个方向受到的撞击作用强,致使微粒又向其它方向运动。这样,就引起了微粒的无规则的布朗运动。布朗运动是英国植物学家布朗在观察液体中浮游微粒运动时发现的随机现象,现在已经成为随机过程理论重要的概念之一。布朗运动是悬浮颗粒永不停息的做无规则运动的现象

  • VCSOASteadyGainTMM
    基于传输矩阵法(TMM)计算VCSOA(垂直腔半导体光放大器)的稳态增益的程序。由于是从将输入端功率Pin作为已知条件,程序用Matlab优化工具箱中的fsolve函数计算了满足边界条件时的输出功率。这对于相关研究开发都是较好的资料。(This is a set of source codes, which are used for calculating the steady state gain of VCSOA based on the transfer matrix method(TMM). Since the input power of the VCSOA is regarded as a already-known condition, this program, the function "fsolve" in the Matlab Optimization Toolbox is used for obtaining the output power of the VCSOA when the input power is at some value. This is a good material for further studying the related problems, especially when using the Matlab for device simulations. )
