There are 3 models of Buck converter closed loops with PWM done in simulink and they work properly

AHP层次分析法计算判断矩阵的最大特征值,有信道编码，调制，信道估计等，GPS和INS组合导航程序。( Calculate the maximum eigenvalue judgment matrix of AHP, Channel coding, modulation, channel estimation, GPS and INS navigation program.)

建立了带硬时间窗车辆路线问题的数学模型，并应用matlab软件检验了其正确性。设计了用遗传算法求解该数学模型的算法思路，即采用自然数编码的方法使得交叉和变异操作得以更加简便的进行(based on GA solve the mutil-objects problem with the help of time window)

这是一个半导体激光器弛豫振荡现象的仿真程序，计算参数和速率方程模型都取自经典教材Semiconductor Lasers(Agrawal 著)，可以作为学习和进一步研究半导体激光器各种动态特性的基础材料。(This is a simulation program by Matlab for calculating the oscilating in semiconductor lasers, in which the rate equation model and the parameters used are all from the classic technical monograph by Agrawal. This could be a basic material for further investigating and studying different dynamic activities of semiconductor lasers. )
