Layout syntax of an Edit Field component in MATLAB App Designer in a grid parent

[poster]

I would like to specify the layout in a grid of an edit field as soon as I create it in MATLAB App Designer.

app.villes1 = uieditfield(app.GHIetPOA_grid, 'text', 'HorizontalAlignment', 'center', ...

              'Editable', 'on', 'Layout', **???**);

I tried using simply [r,c] but this syntax does not seems right. I googled my problem an only founded ways to specify row and column by creating the edit field and specifying the row and column after by dot indexing :

app.villes1.Layout.Row = 2; 

app.villes1.Layout.Column = i+2; 

However, I can't use this because I am actually generating edit field in a for loop and dot indexing is forbidden this way :

function initVilles1(app)

    for i=1:8

        app.villes1(i) = uieditfield(app.GHIetPOA_grid, 'text', 'HorizontalAlignment', ...

        'center', 'Editable', 'on');

        app.villes1(i).Layout.Row = 2; 

        app.villes1(i).Layout.Column = i+2; 

     end

end

Thanks already! (:
