get.wavelet.basis: Wavelet Packet indices for a Wavelet Basis
Description
get.wavelet.basis returns the full set of packet indices relative to a wavelet basis
selected from the wavelet packet table.
Usage
get.wavelet.basis(scale)
Arguments
scale
The maximum scale for which the indices of the wavelet basis are returned.
Tipically this is a positive integer.
Value
A matrix of two columns where each row refers to a different selected packet.
The first index refers to each given scale, the second index refers to the packet
within this level.
Details
This function is used internally by other routines but it might be useful when
the 'classical' wavelet spectral estimation is of interest. The function returns
an object of class LSWPbasis, whose structure is the same to the object produced by
best.basis.
