Dictionary Object For Wavelet Analysis

DESCRIPTION:

Objects of class wp.dict that contain all relevant information for wavelet packet analysis.

GENERATION:

Objects of class "wp.dict" are returned from calling functions wp.dict() .

METHODS:

The class "wp.dict" has methods for the following generic functions:

print, wavelet.name.

STRUCTURE:

The "wp.dict" object is a list with the following components:

VALUE:

wavelet
a character string giving the name of the wavelet. Available orthogonal wavelets are:
coiflet:
"c6", c12", "c18", "c24", "c30"

;

daublet:
"d2", "d4", "d6", "d8", "d10", "d12", "d14", "d16", "d18", "d20";
symmlet:
"s4", "s6", "s8", "s10", "s12", "s14", "s16", "s18", "s20".

Available biorthogonal wavelets are:
bspline:
"bs1.1", "bs1.3", "bs1.5", "bs2.2", "bs2.4", "bs2.6", "bs2.8"

, "bs3.1", "bs3.3", "bs3.5", "bs3.7", "bs3.9" ;

vspline:
"vs1", "vs2", "vs3".

analysis.filter
a list of two vectors: low-pass filter and high-pass filter. Filters for analysis.
synthesis.filter
a list of two vectors: low-pass filter and high-pass filter. Filters for synthesis.
dual
logical flag indicating if dual filter is used for analysis instead of synthesis. In effect only when wavelet matches one of the biorthogonal wavelets.
boundary
a character string giving the boundary rules. Available boundary rules: "periodic", "polynomial", "poly0", "poly1", "poly2", "zero", "reflection", "interval", "infinte" . When boundary="polynomial" or "infinte", boundary has attributes pdeg and pfrac, which give the degree of the polynomial and fraction of data to be used for boundary extension. When boundary="interval", boundary has attribute precondition, which is a logical flag indicating if preconditioning the data.
n.levels
a non-negative integer specifying number of levels in decomposition.
decimate
logical flag indicating if non-decimating transform to be performed.
attr.x
attributes of the original signal.
series.name
the name of the original signal.
n.sample
sample size.
bi.even
boundary matrix for even sample size.
bi.odd
boundary matrix for odd sample size.
fast
logical flag indicating if fast algorithms are called.
