遗传算法求最大值最小值问题的一些实例及其matlab实现。(Some examples of matlab genetic algorithms Maximum Minimum problem.)

lpf实现,可以用于matlab仿真中，将此代码放到matlab工作目录下方可使用(the lpf )

本实验设计了一个《北京、南京、深圳列车查询系统》的图形用户界面。用户可以通过此界面，采用“按车站名称查询”、“按列车车次查询”和“按出发地—目的地查询”三种方式，方便地查询需要的列车信息。界面友好清新，操作方便。(The experimental design was a " Beijing, Nanjing, Shenzhen Train Enquiry System," the graphical user interface. Users can use this interface, a " query by station name" , " Query by Train Train" and " by origin- destination query" three ways to easily check in need train information. Fresh and friendly interface, easy to operate.)

matlab最速下降法，简单的求二次函数的hesse矩阵(steep decent method)

Three matlab-based tools have been developed for the convenient assess- ment of stability conditions for linear and nonlinear systems. The fi rst is a more helpful and defi nitive version of nyquist, which has features of automatic zooming and which displays on the real axis a numeral (‘0’, ‘1’ etc.)
