i need a documentation about creating a Simulink simulation file from Matlab code

I want a book or PDF or other documentation apropos to create a Simulink simulation file from Matlab code

as below

    % Paramètres
    Ts = 0.0005; % Temps d'échantillonnage
    num_outputs = 41; % Nombre de sorties
    modelName = 'GeneratedModelWithScope';

    % Vérifiez si le modèle existe déjà et, le cas échéant, supprimez-le
    if bdIsLoaded(modelName)
        close_system(modelName, 0);
        bdclose(modelName);
    end

    % Création d'un nouveau modèle Simulink
    new_system(modelName);
    open_system(modelName);

    % Ajout du bloc de signal aléatoire
    add_block('simulink/Sources/Random Number', [modelName '/Random Signal'], 'Position', [20, 20, 70, 50]);
    set_param([modelName '/Random Signal'], 'SampleTime', num2str(Ts));
    

    % Ajout des blocs Delay et reliure à la source
    for i = 1:num_outputs
        delay_name = [modelName '/Delay' num2str(i)];
        add_block('simulink/Discrete/Delay', delay_name, 'Position', [100*i, 50, (100*i+ 50), 50+30]);
        
    end
for i = 1:num_outputs
    delay_name = [modelName '/Delay' num2str(i)];
    set_param(delay_name, 'SampleTime', num2str(Ts));
    set_param(delay_name,'Delay', i);


    
     add_line(modelName, 'Random Signal/1', ['Delay' num2str(i) '/1']);
end

    % Ajout du bloc multiplexeur
    mux_pos = [200, 20, 250, 20 + num_outputs*50];
    mux_name = [modelName '/Mux'];
    add_block('simulink/Signal Routing/Mux', mux_name, 'Position', mux_pos);
    set_param(mux_name, 'Inputs', num2str(num_outputs));

    % Reliure des sorties Delay au multiplexeur
    for i = 1:num_outputs
        add_line(modelName, ['Delay' num2str(i) '/1'], ['Mux/', num2str(i)]);
    end

    % Ajout du bloc oscilloscope
    scope_pos = [300, (num_outputs*50)/2 - 40, 370, (num_outputs*50)/2 + 40];
    scope_name = [modelName '/Scope'];
    add_block('simulink/Sinks/Scope', scope_name, 'Position', scope_pos);
    set_param(scope_name, 'NumInputPorts', '41');
    
    % Reliure du multiplexeur à l'oscilloscope
    add_line(modelName, 'Mux/1', 'Scope/1');

    % Ajustement de la vue pour voir tous les blocs
    Simulink.BlockDiagram.arrangeSystem(modelName);

You mean programmatic creation and editing of a Simulink model? See this section of the documentation.
