How to plot the value of a matrix?

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?

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

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
