Hi all, i'm trying to construct a wavelet lifting scheme, but am having some problems: I am unable to get a z1 filter to work, the filter command wont do any good. I know that the z-1 filter can be implemented by : filter([0 1],1,a); Can anybody help me with this? :P

Do you have the Wavelet Toolbox? If so you can implement a lifting scheme where the Laurent polynomial has positive powers of z easily.
