Description Usage Arguments Value References See Also Examples
Given j, n, t are the decomposition level, oscillation index, and time index, respectively, the DWPT is given by
W(j,n,t)=sum(u(n,l) * W(j-1, floor(n/2), 2t+1-l mod N(j-1))),
The variables g and h represent the scaling filter and wavelet filter, respectively. Each filter is of length L. By definition, W(0,0,t)=X(t) where X is the original time series.
