Basic wavelet routines for time series (1D), image (2D)
and array (3D) analysis. The code provided here is based on
wavelet methodology developed in Percival and Walden (2000);
Gencay, Selcuk and Whitcher (2001); the dual-tree complex wavelet
transform (CWT) from Kingsbury (1999, 2001) as implemented by
Selesnick; and Hilbert wavelet pairs (Selesnick 2001, 2002). All
figures in chapters 4-7 of GSW (2001) are reproducible using this
package and R code available at the book website(s) below.
