Create a folder for each iteration and save workspace and figures

Hello, I need to save the workspace and figures for each iteration. The resulting workspace and figures should be placed in a new folder for each iteration. The iterations are a function of two parameters A and B, so I have two 'for' loops.

For IdxParaA=1:length(ParaA)
  For IdxParaB=1:length(ParaB)

                alpha=ParaA(IdxParaA) 
                beta=ParaB(IdxParaB)

    ...stuff to run...

    %HERE NEED TO CREATE A FOLDER AND SAVE BOTH WORKSPACE + FIGURES    
    cd('C:\Output\Results_"value of IdxParaA"_"value of IdxParaB"
    

    cd('C:\Program') 
        end
end

I have 5 values for ParaA and 4 values for ParaB so in the end I need to have 20 folders named as:

C:\Output\Results_1_1

C:\Output\Results_1_2

...

C:\Output\Results_1_4

... ...

C:\Output\Results_5_4

Please let me know if this is not clear or there is a post that answers it

I wouldn’t save them each in a different directory, simply a different .mat file. See the documentation for save, load, and matfile for details. You’ll have all your variables — regardless of type — in each .mat file, and you’ll be able to load all or some of the variables into your workspace as you need them later.

I am posting this for people finding relative answer.

for i = 1:5    
    
    x = rand(10,1) ; 
    y = 3*x + i^2 ;
    plot(x,y,"bo"); hold on;
    a = plot(x,y) ; hold off;
    
    dest_dir = "C:\folder\PROJECT DATA\figure" + i ;
    mkdir(dest_dir);
  
    filename = "plot"+string(i)+".png";
    
    % saveas(fig,filename)
    fig_file = fullfile(dest_dir , filename)
    
    %saveas(a, filename)  %save the file there directory
    saveas( a, fig_file)
    result = "results"+i;
    
    matfile = fullfile(dest_dir, result);
    save(matfile);
    %save(result)
end
