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.
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,
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
