Can you give more info? AFAIK there is no requirement in most of the wavelet functions for the matrix to have a certain size, see for exampel https://www.mathworks.com/help/wavelet/ref/wavedec2.html

In compressed sensing scheme, there is a need to multiply the sensing matrix with sparsifying matrix (I am using wavelet domain as the sparsifying matrix). Just like DCT, Phi = dct(eye(N)) generates an NxN DCT matrix, I want to generate wavelet transform matrix.
