drawwp.default {wavethresh} | R Documentation |
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 |
family |
The family of wavelet you want, see |
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.
