Discret-Wavelet-Transform-got-Daub2-by-Santhana-R
y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level
It returns the matrix of all decompositions and the final approximations.
Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes.
For other wavelets, the filter values alone can be changed or WFILTERS can
be used.
The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author.
Example:
clear all
t=[0:0.0003:8*pi]
x=sin(5000*t)+sin(1000*t)
x=x(1:2^16)
level=5 Fs=1/0.003
d2wavelet(x,Fs,level)
Thanks for Downloading. Don t forget to rate or comment.

vmd
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.)
