get.flat.basis: Wavelet Packet Basis for a single scale

In LSWPlib: Simulation and Spectral Estimation of Locally Stationary Wavelet Packet Processes

Wavelet Packet Basis for a single scale

Description

get.flat.basis returns the full set of packet indices relative to a basis for a single scale from the wavelet packet table.

Usage

get.flat.basis(scale)

Arguments

scale

The scale for which the indices of wavelet packet basis are returned. Typically this is a positive integer.

Details

This function is used internally by other routines but it might be useful when the wavelet packet spectral estimation over a fixed scale is of interest. The function returns an object of class lswpbb, whose structure is the same to the object produced by best.basis.

Value

A matrix of two columns where each row refers to a different selected packet. The first index is the argument scale, the second index refers to the packet within this level.
