In wavethresh: Wavelets Statistics and Transforms

Subsidiary routine that actually computes wavelet packet values

Description

Function computes the values of a given wavelet packet on a discrete grid.

Usage

drawwp.default(level, index, filter.number = 10, family = "DaubLeAsymm",
    resolution = 64 * 2^level)

Arguments

level	The resolution level of the packet you want
index	The packet index of the packet you want
filter.number	The type of wavelet you want, see filter.select
family	The family of wavelet you want, see filter.select
resolution	The number of ordinates at which you want the wavelet packet

Details

Function works by computing a wavelet packet transform of a zero vector. Then inserting a single one somewhere in the desired packet, and then inverts the transform.

Value

A vector containing the "y" values of the required wavelet packet.
