How to otain discrete wavelet transform matrix of any size (eg. 500 instead of 512) in matlab?

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.
