神经网络遗传算法函数极值寻优非线性函数极值寻优(Neural network genetic algorithm optimization function extreme nonlinear function extreme optimization)

一组光纤模型,单模光纤和多模光纤都有，很好用(a lot of fiber mode)

6KV 风力发电机组的诱惑控制中的PI功率控制的具体实例(6KV pi powercontrol)

This code simulate, relay selection using the weak channel on ad-hoc and relay channels.Also power allocation is used for decrease consumed power.

id0的永磁同步电机仿真，可自设置参数，有说明。(Id0 permanent magnet synchronous motor simulation, can be set the parameters, there are instructions.)

利用duffing振子检测微弱信号频率的matlab程序。可以检测与周期策动力频率相差0.03之内的微弱信号频率。信噪比达到-68db(use Duffing oscillator frequency detection of weak signals in Matlab procedures. Can be detected with the cycle driven frequency difference of 0.03 within the weak signal frequency. Signal-to-noise ratio-68db)

ITS ABOUT SOME BASIC MATLAB OPERATION

关于导航定位中的卡尔曼滤波程序。X1，X2分别代表经过转换以后的位置X,Y轴的坐标。V1，V2为其相对应的速度。卡尔曼滤波可以使定位数据更加平滑。(Calman filtering program in navigation and positioning. X1, X2, respectively, after conversion to the position of the X, Y axis coordinates. V2, V1 for its relative speed. Calman filter can make the positioning data more smooth.)
