mpostfilter {wavethresh}R Documentation

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
