WaveThresh Help

accessD.wp

Obtain whole resolution level of wavelet packet coefficients from a wavelet packet object (wp).

DESCRIPTION

Get a whole resolution level's worth of coefficients from a wp wavelet packet object. To obtain packets of coefficients from a wavelet packet object you should use the getpacket collection of functions.

USAGE

accessD.wp(wp, level)

REQUIRED ARGUMENTS

wp: Wavelet packet object.
level: the resolution level that you wish to extract.

OPTIONAL ARGUMENTS

None.

VALUE

A vector containing the coefficients that you wanted to extract.

DETAILS

The wavelet packet coefficients are actually stored in a straightforward manner in a matrix component of a wp object so it would not be too difficult to extract whole resolution levels yourself. However, this routine makes it easier to do. RELEASE Version 3.5.3 Copyright Guy Nason 1994
