mpostfilter: Multiwavelet postfilter

In wavethresh: Wavelets Statistics and Transforms

Multiwavelet postfilter

Description

A multiwavelet postfilter turns a multivariate sequence into a univariate sequence. As such, the postfilter is used on the inverse transform, it is the inverse of an earlier used prefilter.

Not intended for direct user use.

Usage

mpostfilter(C, prefilter.type, filter.type, 
    nphi, npsi, ndecim, nlevels, verbose = FALSE)

Arguments

C	The multivariate sequence you wish to turn back into a univariate one using the inverse of an earlier prefilter operation.
prefilter.type	Controls the type of prefilter (see Tim Downie's PhD thesis, or references therein. Types include Minimal, Identity, Repeat, Interp, default, Xia, Roach1, Roach3, Donovan3 or Linear
filter.type	The type of multiwavelet: can be Geronimo or Donovan3
nphi	The number of father wavelets in the system
npsi	The number of mother wavelets in the system
ndecim	The ndecim parameter (not apparently used here)
nlevels	The number of levels in the multiwavelet transform
verbose	If TRUE then informative messages are printed as the function progresses
