快速傅里叶变换， 频谱的泄露，混叠误差实例的matla程序。(Fast Fourier Transform: In order to reduce the number of DFT calculations of a fast algorithm.)

matlab要求编写函数，并画出图的matlab习题，供大家参考(prepared Matlab functions, and draws a plan of Matlab Exercise, for your reference! !)

此程序是基于小波变换，并利用二维小波变换对图像进行编码(Using two-dimensional wavelet transform for image coding)

Buck变换器是最常用的变换器，工程上常用的拓扑如正激、半桥、全桥、推挽等也属于Buck族，其中Buck变换器补偿网络设计，是开关电源的重要研究课题，本文将针对基于PI控制方式的4A开关电源进行设计和Multisim的仿真研究。(Buck converter is the most commonly used converter on the topology of the project, such as forward, half bridge, full bridge, push-pull, the Buck family, Buck Converter compensation network design is an important research topic of the switching power supply, this paper4A-based PI control switching power supply design and Multisim simulation study)

说明：  免疫算法在配电网故障诊断的应用：随机设置一组故障编码，和三种故障编码，通过免疫算法，求得故障编码属于故障类型的概率(The application of immune algorithm in fault diagnosis of distribution network: a set of fault codes and three kinds of fault codes are set randomly, and the probability of fault codes belonging to fault types is obtained by immune algorithm.)

这个文件是关于分数阶余弦变换的MATLAB代码和分数阶傅里叶变换MATLAB代码，可以用于图像处理加密、滤波等用途，一维的变换实测在即接近整数时会有较大差距，可能算法比较旧，二维的变换没用过，可能和一维的由类似的问题，如果有需要的可试一下，最近我在做关于分数阶傅里叶变换的工作，希望能够交流一下

实数编码的遗传算法，有具体实例，非常好用。(Real number coding genetic algorithm with exaples.It is easy to use)

用介观方法格子Boltzmann计算圆柱绕流(Mesoscopic lattice Boltzmann method with calculated flow around a cylinder)

可以对已有的信号求其循环谱，信号可以通用的。(The cyclic spectrum of the existing signal can be obtained, and the signal can be universal.)
