0-1整数规划有很广泛的应用背景，比如指派问题，背包问题等等，实际上TSP问题也是一个0-1问题，当然这些问题都是NP问题，对于规模较大的问题用穷举法是没有办法在可接受的时间内求得最优解的，本程序只不过是一个练习，得意之处是用递归法把所有解都排列出来。另：胡运权所著的《运筹学基础及应用（第三版）》第97页的例3，我用本程序求解得到的结果是：最优解是x*=(1,0, 0, 0, 0)，最优值是f(x*)=8，但书求得最优解是x*=(1,0, 1, 0, 0)，最优值是f(x*)=4，是不是书中写错了，请大家验证。以下是源程序，大家可以任意使用无版权问题，另外，如果大家有大规模的0-1规划的问题也希望提供给我，谢谢。变量个数至少是3个(0-1 Integer Programming is a very broad background, such as assignment, bags and so on. actually TSP is a 0-1, of course, these problems are NP, for larger problem with the law is not exhaustive approach in an acceptable time frame to obtain the optimal solution. this procedure is only one practice, farewell tour is the method used recursive all of the solutions to show. Another : Hu Yun-author of "operational research, and application base (third edition)" Article 97 of the three cases, I use this procedure to solve the result is : is the optimal solution x = (1,0, 0, 0, 0), the optimal values of f (x*) = 8, but the book is to find the optimum solution x = (1,0, 1, 0, 0), the optimal values of f (x*) = 4, the book is not a mistake, please certification.

有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。(There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.)

该界面可以用来分析控制系统在时域，频域和使用状态空间分析技术。它还提供了在采用极点配置的方法设计一个二阶系统的状态空间设计额外的特征。(This GUI can be used to analze control systems in time domain, in frequency domain and using using state space analysis techniques. It also provides an additonal feature of designing a second order system in state space design using pole placement approach. )

简单的MATLAB对各种文件的读取，适合初学者入门学习使用。(Simple MATLAB to read the various documents, suitable for beginner to learn to use.)

以自动控制原理和汽车理论课程为理论基础，建立了汽车二自由度系统模型以及电动助力转向系统模型，并进行仿真。利用已经建好的车辆模型和转向系统模型，还可以实现与CarSim等车辆动力学软件实现联合仿真。(Based on the theory of automatic control and automobile theory, a vehicle two degree of freedom system model and an electric power steering system model are established and simulated. Using the built vehicle model and steering system model, it can also realize the joint simulation with CarSim and other vehicle dynamics software.)
