PLL的simulink仿真模型，希望能有用，谢谢大家(PLL in simulink simulation models, hoping to be useful, thank you)

一个舰船噪声信号仿真建模的程序，已经测试通过，并且可以实际应用，修改参数即可仿真各类特殊的信号(A ship noise signal simulation and modeling procedures have been tested, and practical application, modify the parameters to simulation of various types of special signal)

这是背包问题的程序，用matlab实现，背包问题是NP完全问题(This is the knapsack problem program, using matlab , knapsack problem is a a NP-complete problem)

说明：  此模型为双向DCDC，可用于电池充放电，燃料电池升降压模拟等。采用PWM控制IGBT管占空比。可直接运行，在其基础上修改简单(This model is a bidirectional DCDC, which can be used for battery charging and discharging, fuel cell buck-boost simulation. PWM control of the IGBT tube duty cycle. Can be run directly, modify it on the basis of simple)

三相静止坐标系变换到dqo坐标系的建模仿真（matlab/simulink）(Three-phase stationary coordinate system transformation to dqo coordinate system modeling and simulation (matlab/simulink))

各种数字调制的GUI程序ASK,FSK,2PSK,QPSK。(ASK,FSK,2PSK,QPSK)

matlab环境下编成的用于回归的支持向量机源程序(svm for regression)

说明：  实现图像的正反傅里叶变换，并用fft实现两幅图像的幅相交换(Amplitude and phase s replacement with fft)

说明：  实现一个以矩阵数为像素点的矩阵的任意角度的转动，程序简易，方便！！！(To achieve a number of pixel matrix of arbitrary angle rotation matrix, the program simple and convenient! ! !)

简易的matlab程序,还请大家多多指教，另求有限元计算光纤模场的matlab程序，请大家指点(some easy programs of matlab)
