plot(yourMatrix)

Yeah, I tried but It does not open the plot

srcFile = dir('C:\Users\agnes\Pictures\POST PROCESSING 4\PP4 TGC-MED RD 100\*.dcm');
pathname = ('C:\Users\agnes\Pictures\POST PROCESSING 4\PP4 TGC-MED RD 100\');


numberofimages = 21; 
numberofroi = 2;


I=dicomread('2'); 
imshow(I)

R = nan(numberofroi,4);
masks=cell(numberofroi,1);

for nr = 1:numberofroi
    h = drawrectangle(gca); wait(h);  
    R(nr,:)=h.Position;
    masks{nr}=h.createMask;
end
roibasket = cell(numberofroi,numberofimages);
meanbasket = nan(size(roibasket));  
for ni = 1:numberofimages
    for nr = 1:numberofroi
        filename=(num2str(ni));       
        
        pileofimages=dicomread(strcat(pathname,filename));
        info=dicominfo(strcat(pathname,filename));
        
        roibasket{nr,ni} = imcrop(pileofimages,R(nr,:));
        meanbasket(nr,ni) = mean( pileofimages(masks{nr})  );    
        devstdbasket (nr,ni) = std2 ( pileofimages(masks{nr})  );
    end
end

for use = 1: numberofimages
    
    Mu = meanbasket(:, use);
    M2 = meanbasket;
    M2(:, use) = NaN; 
     
    th = devstdbasket(:,use); 
    for i = 1 : length(Mu)
        mi = Mu(i);
        di = abs(M2 - mi); 
        [r, c] = find(di <= th);
        fprintf('\n\nLa %da ciste della immagine %d vale %d\n', i, use, mi);
        if length(r) < 1
            fprintf('\n No value found!');
        else 
            fprintf('\n I find the same value!\n');
        end
        for j = 1 : length(r)
            fprintf('\nM(%d,%d)=%d', r(j), c(j), meanbasket(r(j), c(j)));
        end
    end
end
plot (meanbasket) %Why it does not work?

@Agnese Chini, you forgot to attach 2.dcm. Please use the paperclip icon to attach it so we can run your code.

[HelpAStudent]

I can not, because is a dicom image. A dicom image can't be attach right here. Can't you just chek why does not plot? Because the code befor the latest line does the work

[Matt J]

It is not obvious from the posted code why it does not plot. The simplified code below is something you can easily run to prove to yourself that it should work.

meanbasket=rand(4,7);

plot(meanbasket); legend
