added Rice Wavelet Toolbox with my modification, so it can be compiled on newer systems.

+function [x,L] = mirdwt(yl,yh,h,L);
+%    function [x,L] = mirdwt(yl,yh,h,L);
+% 
+%    Function computes the inverse redundant discrete wavelet
+%    transform x  for a 1D or 2D input signal. (Redundant means here
+%    that the sub-sampling after each stage of the forward transform
+%    has been omitted.) yl contains the lowpass and yl the highpass
+%    components as computed, e.g., by mrdwt. In the case of a 2D
+%    signal, the ordering in
+%    yh is [lh hl hh lh hl ... ] (first letter refers to row, second
+%    to column filtering).  
+%
+%    Input:
+%       yl : lowpass component
+%       yh : highpass components
+%       h  : scaling filter
+%       L  : number of levels. In the case of a 1D signal, 
+%            length(yl) must  be divisible by 2^L;
+%            in the case of a 2D signal, the row and
+%            the column dimension must be divisible by 2^L.
+%   
+%    Output:
+%	     x : finite length 1D or 2D signal
+%	     L : number of levels
+%
+%  HERE'S AN EASY WAY TO RUN THE EXAMPLES:
+%  Cut-and-paste the example you want to run to a new file 
+%  called ex.m, for example. Delete out the % at the beginning 
+%  of each line in ex.m (Can use search-and-replace in your editor
+%  to replace it with a space). Type 'ex' in matlab and hit return.
+%
+%
+%    Example 1:
+%    xin = makesig('Leopold',8);
+%    h = daubcqf(4,'min');
+%    L = 1;
+%    [yl,yh,L] = mrdwt(xin,h,L);
+%    [x,L] = mirdwt(yl,yh,h,L)
+%    x = 0.0000 1.0000 0.0000 -0.0000 0 0 0 -0.0000
+%    L = 1
+%  
+%    Example 2:  
+%    load lena;
+%    h = daubcqf(4,'min');
+%    L = 2;
+%    [ll_lev2,yh,L] = mrdwt(lena,h,L); % lena is a 256x256 matrix
+%    N = 256;
+%    lh_lev1 = yh(:,1:N); 
+%    hl_lev1 = yh(:,N+1:2*N); 
+%    hh_lev1 = yh(:,2*N+1:3*N);
+%    lh_lev2 = yh(:,3*N+1:4*N); 
+%    hl_lev2 = yh(:,4*N+1:5*N); 
+%    hh_lev2 = yh(:,5*N+1:6*N);
+%    figure; colormap(gray); imagesc(lena); title('Original Image');
+%    figure; colormap(gray); imagesc(ll_lev2); title('LL Level 2');
+%    figure; colormap(gray); imagesc(hh_lev2); title('HH Level 2');
+%    figure; colormap(gray); imagesc(hl_lev2); title('HL Level 2');
+%    figure; colormap(gray); imagesc(lh_lev2); title('LH Level 2');
+%    figure; colormap(gray); imagesc(hh_lev1); title('HH Level 1');
+%    figure; colormap(gray); imagesc(hl_lev2); title('HL Level 1');
+%    figure; colormap(gray); imagesc(lh_lev2); title('LH Level 1');
+%    [lena_Hat,L] = mirdwt(ll_lev2,yh,h,L);
+%    figure; colormap(gray); imagesc(lena_Hat); 
+%                            title('Reconstructed Image');

+%    Warning! min(size(yl))/2^L should be greater than length(h)
