%WAVEREC2  Multilevel 2-D wavelet reconstruction.
%   WAVEREC2 performs a multilevel 2-D wavelet reconstruction
%   using either a specific wavelet ('wname', see WFILTERS) or
%   specific reconstruction filters (Lo_R and Hi_R).
%
%   X = WAVEREC2(C,S,'wname') reconstructs the matrix X
%   based on the multi-level wavelet decomposition structure
%   [C,S] (see WAVEDEC2).
%
%   For X = WAVEREC2(C,S,Lo_R,Hi_R),
%   Lo_R is the reconstruction low-pass filter and
%   Hi_R is the reconstruction high-pass filter.
%
%   NOTE: If C and S are obtained from an indexed image analysis
%   (respectively a truecolor image analysis) then X is an
%   m-by-n matrice (respectively an m-by-n-by-3 array).
%   For more information on image formats, see the reference
%   pages of IMAGE and IMFINFO functions.
