pso-pid调节matlab程序

说明：  自学Matlab必备的_60_个小程序代码,自己看吧!很好的资源!!!!!!(Matlab Programe 60)

matlab to zemax program

simulink实例,非线性控制实例,对非线性的学习非常有用，(Nonlinear Control Example，it is very useful for us.The dynamic control model of a two-link robot arm in a vertical plane is shown )

加入重复控制，用谱方法计算流体力学一些流动现象的整体稳定性,部分实现了追踪测速迭代松弛算法。( Join repetitive control, Spectral methods of computational fluid dynamics flow of some of the overall stability of the phenomenon, Partially achieved tracking speed iterative relaxation algorithm.)

可以用于二维图像评估程序，若稍微加改进可以作为识别方法(Two-dimensional image can be used in the assessment process, if a little can add to improve the method as a means of identification)

说明：  这个程序可以产生一个6阶的低通巴特沃思滤波器，截止频率是45Hz，你也可以用它来对信号进行滤波，并比较滤波前后的信号功率谱。(This program can generate a six-order low-pass Butterworth filter, cut-off frequency is 45Hz, you can also use it to filter the signal and to compare before and after filtering the signal power spectrum.)

Implements the 1st and 2nd order Gaussian derivative steerable filter in matlab.The oriented first order derivative can be obtained by taking the dot product of a unit vector oriented in a specific direction with the gradient. The basis filters are the partial derivatives of a 2D Gaussian with respect to x and y

用蒙特卡洛模拟来迭代1000次以后，计算10天后的VaR,特色就是对里面的方差和均值进行差分。里面有详细步骤和方法。(Using monte carlo simulation to iteration after 1000 times, calculate the VaR after 10 days,the characteristic of model is that calculating the the variance and mean 不by difference.There are detailed steps and methods)

课程设计用到的qpsk，包括qpsk信号的调制与解调，可运行，有图(Curriculum design qpsk used modulation and demodulation, can be run, there are plans。)
