Is there a way to iterate through numbered UI components in app designer?

I have the following code in an appdesigner app that allows users to select multiple files (up to 10), read them, plot data on a UI axis, and report values in a UI table. All of the selected files will be included in the table and plot, but the user needs the option to exclude some of the data from statistical analysis that is performed in a different callback. I've accomplished this by using check boxes to the left of each row of the table (named app.CheckBox_# where # = 1-10).

for i = 1:numel(filename)   
    app.data.suite(i).spec = readcell([pathname, filename{i}]); 
    
    % Read in force and displacement data
    for k = 2:length(app.data.suite(i).spec)            
        app.data.AxDisp(i).vec(k-1) = app.data.suite(i).spec{k,3};
        app.data.AxForce(i).vec(k-1) = app.data.suite(i).spec{k,2};
    end
    
    %Plot each data set
    plot(app.UIAxes2, app.data.AxDisp(i).vec,app.data.AxForce(i).vec,'LineWidth',1);
    
    %Calculate parameters
    app.data.maxload(i) = max(app.data.AxForce(i).vec); %lbs
    app.data.thickness(i) = cell2mat(app.data.suite(i).spec(4,8));
    app.data.diameter(i) = cell2mat(app.data.suite(i).spec(3,8));       
    
    %Determine strength
    switch app.PlatenTypeDropDown.Value
        case 'Curved'
            app.data.strength(i) = (1.272*app.data.maxload(i))/(pi*app.data.diameter(i)*app.data.thickness(i));
        case 'Flat'
            app.data.strength(i) = (2*app.data.maxload(i))/(pi*app.data.diameter(i)*app.data.thickness(i));
    end 
    
    %Populate UI table
    app.UITable.Data(i,2) = num2cell(app.data.maxload(i));
    app.UITable.Data(i,3) = num2cell(app.data.strength(i));       
end 

I would like to add a section in the above loop that would toggle on each numbered check box based on the same numel(filename) condition as shown below.

for i = 1:numel(filename)
    app.Checkbox_(i).Value = 1
end

Is there a way to iterate over numbered checkboxes (and other numbered UI components)?

for i = 1:numel(filename)
    app.(sprintf('Checkbox_%d',i)).Value = 1;
end

Of course, you can put the checkboxes in an array, say in your startupFcn or whenever the set of checkboxes changes:

app.all_Checkbox = [app.Checkbox_1 app.Checkbox_2 app.Checkbox_3]; % etc.

and index into that array:

for i = 1:numel(filename)
    app.all_Checkbox(i).Value = 1;
end

Thank you for the quick response. This works great!

You're welcome!
