说明：  该模型设计的是AC-DC换流器，能够将交流电转换为直流电压，用于整流控制(AC-DC converter)

基于MATLAB的分形阵列程序。运用的不同实现方法可以帮助初学者熟悉分形阵列的matlab实现！(MATLAB-based fractal array program. Use of different methods that can help beginners familiar fractal array matlab to achieve!)

基于量子遗传算法的函数寻优算法的Matlab程序实现(Based on quantum genetic algorithm function optimization algorithm Matlab procedures)

本程序用来求有向网络中的最大流和最小费用的问题。这里最小费用是在可能有多个最大流的基础上优化得到的。故前提条件是最大流，如果没有没有最大流，可以不运输，成本为0，那就没有意义了。(This program used to beg for the maximum flow to the network and the minimum cost. Here is the minimum cost in May have multiple maximum flow based on optimization get. So premise condition is maximum flow, if no no maximum flow, can not transport, the cost of 0, that is no sense. )
