- I am really not sure how to go about this and any help would be great. I have the GUI set up, but not sure what type of text box to use or how to set it to display

function YourGUI
FigH = figure('Name', 'Your GUI', ...
'IntegerHandle', 'off', ...
'MenuBar', 'none', ...
'NumberTitle', 'off', ...
'Resize', 'off', ...
'Units', 'pixels', ...
'Position', [200, 200, 300, 120], ...
'NextPlot', 'add');
DispH = uicontrol('Style', 'edit', 'String', '', ...
'Enable', 'inactive', ... % Cannot be edited
'Position', [10, 60, 280, 50], ...
'FontSize', 24, 'HorizontalAlignment', 'Center');
ButtonH = uicontrol('Style', 'PushButton', 'String', 'Click on me', ...
'Position', [50, 10, 200, 30], ...
'FontSize', 16, ...
'Callback', {@ButtonCB, DispH});
end
function ButtonCB(BunttonH, EventData, DispH)
Num = randi([0, 10000]); % Integer
% Or: Num = rand * 10000; % Floating point
set(DispH, 'String', sprintf('%g', Num));
end

Create a uicontrol('style', 'text') with appropriate 'Units' and 'Position' setting. Record its handle somewhere. Then each time the button is pressed, create a random number in the appropriate range and set the String property of the uicontrol to the number.
