hi, i want use a dyadic wavelet transform that was implemented using filters proposed by Mallat(1989).

could you help me please

Hi Nasim, do you have the Wavelet Toolbox? The wavelet transform implemented in dwt.m (and the multi-level version wavedec ) is the pyramid algorithm proposed by Mallat.

Also, see the toolbox provided by Stanford professor Dave Donoho and colleagues:

http://www-stat.stanford.edu/~wavelab/

In that software, fwt_po.m implements Mallat's algorithm.
