Cohen-Daubechies-Fauraue 9-7 Wavelet Transforms . CDF小波分解matlab源代码-Cohen-Daubechies - Fauraue 9-7 Wavelet Tr ansforms. CDF wavelet decomposition Matlab source code

Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the w

代码主要计算Daubechies紧支集滤波器系数L0_d和H1_d,然后采用这两个系数对信号进行小波分解-The main calculation code compactly supported Daubechies filter coefficients L0_d and H1_d, then the use of these two coefficients of wavelet decomposition signals

Daubechies, db1 小波分解与重构-Daubechies, db1 wavelet decomposition and reconstruction

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
