HOW i can i display a concatenated image in one figure intead of 3*3 figure

hello evryone , my project is compression image document , first i have to segmente text and background and compresse each one séparately.

i have successfully segment but i have a probleme to display results. THE IMAGE RESULTING IS MULTIPLIED 3*3 , here is my part of my progreme and i will joit my full programme

wd = pwd;%pour récupérer l'image de dossier
cd('C:\Users\HP\Desktop\compression\subimavantplan') ; % path to the icons 
D = dir;
C = {'.tif';'.jp';'.png';'.bmp'};  % pick all possible images from the path 
idx = false(size(D));
for ii = 1:length(C)
    idx = idx | (arrayfun(@(x) any(strfind(x.name,C{ii})),D));
end
D = D(idx);   % image structure array 
L = length(D); % total files 
% read the first file 
data = imread(D(1).name) ;
wholeBlockCols1=wholeBlockCols;
iwant = data ; 
iwant1 =zeros(h1,h2,3);
az=2;
for i1=1:wholeBlockRows
    for i2=az:wholeBlockCols1% loop for each image 
        if (i1==1)
            disp(D(2).name) ;  
            data = imread(D(2).name) ;
            iwant = [iwant,data] ;  % concatenate columns
        else
            disp(D(i2).name) ;  
            data = imread(D(i2).name) ;
            iwant = [iwant,data] ;  % concatenate columns
            disp('row concatenated')
        end
    end
    if (i1==1)
        iwant1 = iwant;    % concatenate row
        az=az+wholeBlockCols;
        wholeBlockCols1=wholeBlockCols1+wholeBlockCols;
        iwant=zeros(BlockSize,BlockSize,3);
        iwant=imread(D(az-1).name) ;
    else
        iwant1=[iwant1;iwant]; 
        az=az+wholeBlockCols
        if(az<=TOTAL_BLOCKS)
            if(wholeBlockCols1<=TOTAL_BLOCKS)
                wholeBlockCols1=wholeBlockCols1+wholeBlockCols;
                
                iwant=imread(D(az-1).name) ;
            end
        end
    end    
end
