Detailed Description

template<class T> class packdata

The packdata class is a container for the core information for a wavelet packet transform node.

This class serves as the base class for the packnode class. It is also the element used in the list that results from the wavelet packet transform. This list represents the data in a minimal for, relative to the wavelet packet transform cost function.
