How can i organize the images in my code?

Hi, I just wrote a code for the recognition of handwritten digits but I have encountered one problem. In my code i want to show images and diagrams right below the corrispondent section of the code. For instance i decided to use a for loop in order to show all the different ten digits, but when i run the code the images go to the end of the whole code, how can i solve this problem? If it can help I'll share the code, let me know if the same thing happen to you as well. The dataset can be found here http://archive.ics.uci.edu/ml/datasets/Optical+Recognition+of+Handwritten+Digits

Y_tra = load('optdigits.tra');     %carico il training set
Y_tes = load('optdigits.tes');     %carico il test set
features = 1:64;
Nfeatures = length(features);
N = size(Y_tra,1);
X = Y_tra(:,features);
Y_class = Y_tra(:,65);       %indica le classi nel training set
class_labels = categorical(unique(Y_class));  %vediamo quante classi ci sono e le trasformiamo in dato categorical
Ncl = length(class_labels);
Y_class_ones = zeros(Ncl,N);    %per usare alcune funzioni bisogna esprimere i dati come matrici, con 1 in corrispondenza della classe (righe) per ogni item (colonne)
for c=1:Ncl
    Y_class_ones(c,find(Y_class==c-1))=1;
end

figure                         %utilizzo un ciclo for nel test set per mostrare le 10 cifre
for i=1:10
    subplot(2,5,i)
    imagesc(reshape(Y_tes(i,1:64),8,8)');
    colormap("gray");
    axis square;
    caption = sprintf('#%d', i-1);
    title(caption);

Hi @Fabrizio Lepori,

Looks like Matlab Live Script can help with what you want to achieve. Please check the following Documentation link

You can check this video which explains what a Matlab Live Editor is.

You can also check the following video on YouTube.

Hi, thanks for your answer, I am already using a Live Script, but when i run my code all the images go to the end of the code.

Hi @Fabrizio Lepori,

Is it because all of the above code is in 1 section ?

Check for the "Section" group, click on "Section Break".

You need to move the code where you want to display images into a seperate section so that, that particular section has its own output.
