Question: Help needed in Multiwavelet Transforms

I was trying to imp lement the GHM Multiwavelet Transform for 1-D
signals in MATLAB. Even though I was able to achieve perfect
reconstruction of my signal from all the decomposition coefficients,
I have problems of the reconstruction becoming highly noisy when I
reconstruct after setting a few of the insignificant decomposition
coeffcients to zero. I am not sure if the decomposition/reconstruction
procedure I am using is right. I would appreciate it if someone could
send me small MATLAB programs for 1-D multiwavelet decomposition and
reconstruction. My e-mail address is
