该实例主要功能： 1、演示了GUI界面的布局和效果； 2、演示了togglebutton、pushbutton对simulink模块参数的设置方法； 3、演示了Edit text 和slider的联合使用，及利用edit text 和slider 对simulink 参数的动态修改； 4、演示了simulink参数在GUI上的显示和更显； 5、语句进行了注释，为便于编译没用中文，大家凑或者看吧！(The main functions of examples: 1, presentation of the layout of the GUI interface and effectiveness 2, demonstrated togglebutton, pushbutton module to simulink Ways parameters 3, Edit text and to demonstrate the joint use of slider, and the use of the slider and edit text simulink dynamic parameters modified 4, demonstrated on simulink parameter GUI at the display and more 5, statement to the Notes, in order to facilitate the compiler no English, or U.S. Check it out together!)

matlab仿真qpsk在高斯信道和瑞利衰落信道下的误码率,做的还不错 (qpsk matlab simulation in AWGN channel and Rayleigh fading channel bit error rate, doing pretty good)

带延迟系统的PID控制算法，整定方法为N-Y整定，对象为G（s）=e^(-5s)/(s+1)(Delay system with PID control algorithm, NY tuning tuning method, the object is G (s) = e ^ (-5s)/(s+1))

说明：  遗传算法的主要程序，只要修改其中的目标函数即可以得到我们想要的结果(The main program of genetic algorithms, as long as modify the objective function that can get the results we want)
