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.
