single degree of freedom vibration unbalance

说明：  采用AR模型，估计功率谱密度，包含实测数据(The AR model is adopted to estimate the power spectral density, including the measured data)

说明：  此程序用于做全息实验时，先把全息图再现得到实像，在对实像双线差值，三内差值和中值滤波的办法来提高再现图质量(This program uses the difference between two-, three within the margin and median filtering approach to improving the quality of image scaling)

用来计算混沌时间序列的延迟时间,It s applied to calculate the delay time of(Used to calculate the delay time of chaotic time series, It s applied to calculate the delay time of)

说明：  高斯分布期望优化（em）算法matlab实现，流量矩阵模型(Optimization of Gaussian distribution expectations (em) algorithm matlab realized, the flow matrix model)

This model defines the spectrum sensing in cognitive radio applications

对ising模型的模拟，这是二维的情况，对于学物理的人很重要的。(Ising model for the simulation, which is two-dimensional case, for physics, it is very important.)

说明：  VMD是通过迭代搜寻变分模型（具体怎么搜寻，请亲们自己看，我主要讲他的大概）最优解， 来确定我们所知的模态uk(t)及其对应的中心频率ωk和带宽。 每个模态都是具有中心频率的有限带宽（就是在频域中有在一定的宽度）。所有模态之和为源信号。(VMD is to determine the modal UK (t) and its corresponding central frequency, k and bandwidth by iteratively searching for the optimal solution of the variational model (see dear friends for details, and I will mainly talk about his approximate solution). Each mode is a finite bandwidth with a central frequency (that is, a certain width in the frequency domain).The sum of all modes is the source signal.)

数据挖掘中聚类算法之DBSCAN算法的matlab实现。(Data mining clustering algorithm of DBSCAN algorithm matlab realize.)
