function [t,x] = wpjoin(t,node) %WPJOIN Recompose wavelet packet. % WPJOIN updates the wavelet packet tree after % the recomposition of a node. % % T = WPJOIN(T,N) returns the modified tree T % corresponding to a recomposition of the node N. % % T = WPJOIN(T) is equivalent to T = WPJOIN(T,0). % % [T,X] = WPJOIN(T,N) also returns the coefficients % of the node. % % [T,X] = WPJOIN(T) is equivalent to [T,X] = WPJOIN(T,0). % % See also WPDEC, WPDEC2, WPSPLT. % M.
