When I run the following code:

for i=1:3

   for niter=1:2  
        img_filtree=smooth_diffusion(I,edgestop(i),'dir',5,niter,0.25);
%       figure(1),imshow(img_filtree);
%       saveas(figure(1), strcat('Résultats\','img_filtree',num2str(niter),'_edgestop',num2str(i),'.tif'));
        imwrite(img_filtree,strcat('Résultats\','img_filtree_',num2str(niter),'-edgestop',num2str(i),'.tif'));%   
        peaksnr{i,niter}=psnr(img_filtree,Isynth)
        snr{i,niter}=psnr(img_filtree,Isynth)
%       [peaksnr,snr] = psnr(img_filtree,Isynth)
        Ed=edge(img_filtree); 
%       F= pratt(Ea,Ed);
        F{i,niter}= pratt(Ea,Ed) 
        filename = 'testdata.xlsx';
        A = {'PSNR','SNR','FOM'; peaksnr{i,niter}, snr{i,niter},F{i,niter}};
%       sheet = 2;
        xlRange = 'A1';
%       xlswrite(filename,A,sheet,xlRange)
        xlswrite(filename,A,xlRange)
   end
end

I got just the final result

I hope to get your question right. You want to save your results in an excel sheet and you are concerned that your results get overwritten each time, correct? If this is the case and you do not care about the layout, you could simply predefine the cells in which you results are saved in. Put

mycells = {'A1','E1','I1';'A4','E4','I4'};

before the loops and then instead of xlRange = 'A1' you write

xlRange=mycells{niter,i};

Does this solve your problem?

Thanks Bastien Dietemann for your reply but this solotion can't solve the problem

mycells = {'A1','E1','I1';'A4','E4','I4'};
for i=1:3
 for niter=1:2
        img_filtree=smooth_diffusion(I,edgestop(i),'dir',5,niter,0.25);
%       figure(1),imshow(img_filtree);
%       saveas(figure(1), strcat('RÃ&copy;sultats\','img_filtree',num2str(niter),'_edgestop',num2str(i),'.tif'));
        imwrite(img_filtree,strcat('RÃ&copy;sultats\','img_filtree_',num2str(niter),'-edgestop',num2str(i),'.tif'));%   [peaksnr1,snr1] = psnr(img_filtree1,Isynth)
        peaksnr{i,niter}=psnr(img_filtree,Isynth)
        snr{i,niter}=psnr(img_filtree,Isynth)
        Ed=edge(img_filtree); 
        F{i,niter}= pratt(Ea,Ed)
        filename = 'testdata.xlsx';
        A = {'PSNR','SNR','FOM'; peaksnr, snr,F};
%         sheet = 2;
        xlRange=mycells{niter,i};
%         xlRange = 'A1';
%         xlswrite(filename,A,sheet,xlRange)
        xlswrite(filename,A,xlRange)
   end
end
I want a table like this:

Okay, let's have another try. I don't have your functions so I cannot test your Version, but this should work.

filename = 'testdata.xlsx';
xlswrite(filename,{'iteration'},1,'A2');
xlswrite(filename,{'edgestop1'},1,'C1');
xlswrite(filename,{'edgestop2'},1,'F1');
xlswrite(filename,{'edgestop3'},1,'I2');
xlswrite(filename,{'PSNR' 'SNR' 'FOM'},'B2:D2');
xlswrite(filename,{'PSNR' 'SNR' 'FOM'},'E2:G2');
xlswrite(filename,{'PSNR' 'SNR' 'FOM'},'H2:J2');
max_niter = 2;
%create destinations
mycells=cell(max_niter,3);
for i =1:max_niter
  mycells{i,1}=sprintf('B%i:D%i',i+2,i+2);
  mycells{i,2}=sprintf('E%i:G%i',i+2,i+2);
  mycells{i,3}=sprintf('H%i:J%i',i+2,i+2);
end
for i=1:3
for niter=1:max_niter
      img_filtree=smooth_diffusion(I,edgestop(i),'dir',5,niter,0.25);
%       figure(1),imshow(img_filtree);
%       saveas(figure(1), strcat('RÃ&copy;sultats\','img_filtree',num2str(niter),'_edgestop',num2str(i),'.tif'));
      imwrite(img_filtree,strcat('RÃ&copy;sultats\','img_filtree_',num2str(niter),'-edgestop',num2str(i),'.tif'));%   [peaksnr1,snr1] = psnr(img_filtree1,Isynth)
      peaksnr{i,niter}=psnr(img_filtree,Isynth);
      snr{i,niter}=psnr(img_filtree,Isynth);
      Ed=edge(img_filtree); 
      F{i,niter}= pratt(Ea,Ed);
      A = {peaksnr, snr,F{i,niter}};
      xlRange=mycells{niter,i};
      xlswrite(filename,A,xlRange)
 end
end
