wavethresh (version 4.6.1)

wpst2m: Converts a nondecimated wavelet packet object to a (large) matrix with packets stored as columns

Description

Takes a nondecimated wavelet packet transform, takes the packets one packet at a time and stores them in a matrix. The packets are rotated on extraction and storage in the matrix in an attempt to align them, they are also optionally transformed by trans. The rotation is performed by compgrot.

Note that the coefficients are of some series, not the basis functions themselves.

Usage

wpst2m(wpstobj, trans = identity)

Arguments

wpstobj

The nondecimated wavelet packet object to store

trans

The optional transform to apply to the coefficients

Value

• A list, of class w2m, with the following components:
• m
  The matrix containing the packets
• level
  A vector containing the levels from where the packets in m come from
• pktix
  A vector containing the packet indices from where the packets in m come from
• nlevelsWT
  The number of resolution levels from the original wpst object
