Wavelet Packet Crystal Objects

DESCRIPTION:

Objects of class wp.crystal or wp.nd.crystal that are building blocks of wavelet packet analysis.

GENERATION:

Objects of class "wp.crystal" are returned from calling functions wp.crystal(), wp.nd.crystal() or using [[ to subscript an object of "crystal.vector" or "ptable". Objects of class "wp.nd.crystal" are returned from calling function wp.nd.crystal() or using [[ to subscript an object of "crystal.vector" when decimate=FALSE.

METHODS:

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

[, [[, bandwidth, center, freq.bandwidth, freq.center, plot, print, reconstruct, shrink, summary, eda.plot, wavelet.name . The class "wp.nd.crystal" has methods for the following generic functions:

print.

INHERITANCE:

Class "wp.nd.crystal" inherits from class "wp.crystal".

STRUCTURE:

The "wp.crystal" object is a vector with the following attributes:

VALUE:

crystal.name
name of the crystal.
shift
index of the first coefficient.
dictionary
the usual wp.dict object containing all relevant information.
odd
logical flag indicating if the parent crystal is of odd length.
