You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: callBoxDeleteCallback.m
    path of file: ./repos/DeepSqueak/Functions
    
    the code of the file until where you have to start completion: function callBoxDeleteCallback(rectangle,
    
function choosedialog(rectangle,handles)

hObject = handles.figure1;
axes_position = get(handles.focusWindow, 'Position');

axes_x_lim = xlim(handles.focusWindow);
axes_y_lim = ylim(handles.focusWindow);
position = get(rectangle, 'Position');
tag = get(rectangle, 'Tag');

dialog_width = 354;
dialog_heigth = 154;

rect_x_relative_to_axes = (position(1) + position(3) - axes_x_lim(1)) / (axes_x_lim(2) - axes_x_lim(1));
rect_y_relative_to_axes = (position(2) + position(4) - axes_y_lim(1)) / (axes_y_lim(2) - axes_y_lim(1));

set(hObject,'Units','Pixels');
fig_pos = get(hObject, 'Position');

x_position = fig_pos(1) + fig_pos(3) * (axes_position(1) + axes_position(3)*rect_x_relative_to_axes);
y_position = fig_pos(2) + fig_pos(4) * (axes_position(2) + axes_position(4)*rect_y_relative_to_axes) - dialog_heigth;

%Make sure the dialog stays within the figure
x_position = min(x_position,fig_pos(3)-dialog_width);
y_position = min(y_position,fig_pos(4)-dialog_heigth);

d = dialog('Position',[x_position y_position dialog_width dialog_heigth],'Name',['Change label for call ' tag],'Units','normal');

% Get the number of rows to columns
n_columns = floor(sqrt(length(handles.data.settings.labels)));
n_rows = ceil(length(handles.data.settings.labels) / n_columns);

button_width = 1 ./ n_columns;
button_height = 1 ./ n_rows;
label_index = 0;
padding = .1;

for c = 1:n_columns
    for r = n_rows:-1:1
        label_index = label_index + 1;
        if label_index > length(handles.data.settings.labels)
            continue
        end
