wavelet
此程序用提升法实现第二代小波变换
用的是非整数阶小波变换
采用时域实现,步骤先列后行
正变换：分裂，预测，更新；
反变换：更新，预测，合并
只做一层（可以多层，而且每层的预测和更新方程不同）(This procedure achieved by lifting the second generation wavelet transform with a non-integer order wavelet transform time-domain realization of transformation steps, then over are: split, predict, update inverse transform: Update, forecasting, consolidation only a layer of ( can be multi-layer, and each prediction and update equations are different))

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)
