Function computes the values of a given wavelet packet on a discrete grid.
drawwp.default(level, index, filter.number = 10, family = "DaubLeAsymm",
resolution = 64 * 2^level)
The resolution level of the packet you want
The packet index of the packet you want
The type of wavelet you want, see filter.select
The family of wavelet you want, see filter.select
The number of ordinates at which you want the wavelet packet
A vector containing the "y" values of the required wavelet packet.
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.
