- function [t,x] = wdtjoin(t,node)
- %WDTJOIN Recompose wavelet packet.
- % WDTJOIN updates the wavelet packet tree after
- % the recomposition of a node.
- %
- % T = WDTJOIN(T,N) returns the modified tree T
- % corresponding to a recomposition of the node N.
- %
- % T = WDTJOIN(T) is equivalent to T = WDTJOIN(T,0).
- %
- % [T,X] = WDTJOIN(T,N) also returns the coefficients
- % of the node.
- %
- % [T,X] = WDTJOIN(T) is equivalent to [T,X] = WDTJOIN(T,0).
