- function tnd = split(t,node,x,varargin)
- %SPLIT Split (decompose) the data of a terminal node.
- % TNDATA = SPLIT(T,N,X) decomposes the data X
- % associated to the terminal node N of the
- % wavelet tree T.
- %
- % TNDATA is a cell array (ORDER x 1) such that
- % TNDATA{k} contains the data associated to
- % the k-th child of N.
- %
- % The method uses DWT for one-dimensional data.
- %
- % This method overloads the DTREE method.
