We do Wavelet transform in image processing. The code below is one example.

[C,S] = wavedec2(X,2,'bior3.7');

In that decomposition, the filter 'bior3.7' is an array,

how to have a matrix of wavelet filter in 2D wavelet decomposition?

How can I have 'db1' 2D matrix filter for wavedec2?

Thanks.

Use dect2 [cA,cH,cV,cD] = dwt2(x,'db1','mode','sym');
