How to save and update a simulink model via code?

I am creating a function that checks simulink models for errors,reports them, and corrects them. I would like for the program to also be able to update and save the model once it has completed it tasks, How would I do that?

For example in this function the objective is to check testpoints lines and make sure the log data box is checked and the correct class is used. Once that is done I want it to update and save the model.

function testPointCheck( app )
    %%%%%%App Specific Stuff
    % stop the timer while we are running
    stop(app.projectTimer);
    % disable the generate button while we are running
    %app.RunCleanupButton.Enable = 'off';	
    app.StatusArea.Value = 'Running test point check function. This can take awhile...';
    filename  = app.TopModelEditField.Value;
    [folder, system, extension] = fileparts(filename);
    load_system(system);
    %%%%%%End App Specific Stuff
    %Remove Old whitespace findings mat file
    projects = slproject.getCurrentProjects;
    projectRoot = projects.RootFolder;
    saveFolder = [projectRoot '\scripts'];
    saveFileFullName = [saveFolder '\testPoint.mat'];
    warning('off','all')
    delete (saveFileFullName);
    %delete ('ErrorReport.xlsx');
    %xlswrite('ErrorReport.xlsx','ErrorReport');
    warning('on','all')
    %allLines=find_system(system,'FindAll','on','type','line');
    allLines = recursiveModelReferenceLines(char(getfullname(system)),[]);
    testPointLines = [];
    names = [];
    
    %{
        In this section the program is searching for lines with the test point
        Box checked, stores them in a separate variable and retrieves their
        name. After that the program corrects the errors
    %}
    for i=1:length(allLines)
        point = get(allLines(i),'TestPoint');
        if point ==1
            testPointLines = vertcat(testPointLines,allLines(i));
            %names =vertcat(names,get(testPointLines,'Name'));
            
            cellarray =[get_param(testPointLines,'Parent') get(testPointLines,'Name')];
            names = cellarray(:,2);
        end
    end
    if (~isempty(names))
        save(saveFileFullName,'testPointLines')
        varName = {'Model','Line'};
        for i=1:length(testPointLines)
            unLoggedLines = get(testPointLines(i),'DataLogging');
            Class = get(testPointLines(i),'StorageClass');
            isClassGood = strcmp(Class, 'ExportedGlobal');
            if unLoggedLines ==0
                T = table(cellarray(:,1),cellarray(:,2),'VariableNames',varName);
                writetable(T,'ErrorReport.xlsx','Sheet','unLoggedLines');
                set(testPointLines(i),'DataLogging',1)
            end
            if isClassGood ==0
                S = table(cellarray(:,1),cellarray(:,2),'VariableNames',varName);
                writetable(S,'ErrorReport.xlsx','Sheet','incorrectStorageClass');
                set(testPointLines(i),'StorageClass','ExportedGlobal')
            end
        end
        set_param(gcs,'SimulationCommand','Update')
        
    end
    save_system(system);
end

You already have the lines

set_param(gcs,'SimulationCommand','Update');
save_system(system);

Are you getting any error?

No I am not, but I still have to manually save and update the model. For some reason the commands are not be activated or I am not using them correctly.

Update: I am not geeting this error

The specified top model was not saved due to the existence of dirty referenced models (for example,

'lm6Core/parameters'). Use the save_system name-value pair 'SaveDirtyReferencedModels','on' to

save the specified top model as well as all the dirty referenced models.
