时频分析中的cohen类中最基本的双线性时频分布式wigner-ville分布，由于在该分布中不含窗函数，因此避免了短时窗傅里叶变换时间分辨率、频率分辨率相互牵制的矛盾(Time-frequency analysis of the Cohen class of bilinear time-frequency distribution is the most basic Wigner-Ville distribution, because the function in the distribution is not included in the window, so as to avoid the contradiction of short-time window Fourier transform time resolution, frequency resolution of each other)

非均匀傅里叶变换，此程序仿真了非均匀采样信号的非均匀傅里叶变换(Non-uniform Fourier transform, this non-uniform Fourier transform of a non-uniform sampling signal simulation program)

these document are papers which talk about the benefict of the use of the fft for localisation

图形图像 匹配。当有两个图像时，程序计算一个图像的不变量，然后跟两一个图像比对，然后输出他们是否匹配。(This codes are for images matching when you have two or more images taken under different lighting, rotation...)

用matlab完成计算机控制中的连续系统与离散系统的实验，其间用到了关于控制技术中的各种函数，附带实验报告！(Matlab completed by computer-controlled experiments in continuous systems with discrete systems, during use of the various functions on the control technology, with a test report!)

对遗传算法思想的理解和认识,对一个函数求其最小值，采用遗传算法的交叉，变异等特征进行优化求解(Genetic algorithms for understanding and awareness of thoughts, seeking the minimum of a function, using genetic algorithm crossover and mutation characteristics of the optimal solution)

求信号的时频熵，对非平稳信号进行emd分解后，求时频熵，得出其故障特征(For the signal s time-frequency entropy, the nonstationary signals are EMD decomposition, and time-frequency entropy, the fault feature)
