how to find out biorthogonal wavelet matrix

Hai ,I am working in compressed sensing problem ,Here I would like to find out the transform matrix of biorthogonal wavelet .By this I mean that if I multiply with that matrix with my input signal I have to get the biorthogonal wavelet transform of the input.I know wavedec will directly do this ,I am working in compressed sensing so I wish to take the matrix and to do some manipulations..
