How to indicate that GUI is busy running?

I would like to know how to indicate in my GUI that MATLAB is currently busy running some piece of code (e.g. a long computation). Currently, there is no indication in the GUI that the code is running, causing the user to wonder whether it is working or just not responsive.

Hi Kyle,
two typical main ways to do this: in your callback do
set(handles.figure1, 'pointer', 'watch')
drawnow;
% your computation
set(handles.figure1, 'pointer', 'arrow')
This shows the hour glass during the callback. If the callback indeed takes longer, use function "waitbar" to indicate progress ...

I tried doing this and it is giving this error Error using matlab.ui.control.UIControl/set There is no pointer property on the UIControl class.
Error in Control>error_Callback (line 435) set(handles.error, 'pointer', 'watch')
What does it mean?

You can only set the Pointer for a figure, not for a uicontrol.
fig = ancestor(handles.error, 'figure');
oldpointer = get(fig, 'pointer');
set(fig, 'pointer', 'watch');
drawnow;
% your computation goes here
set(fig, 'pointer', oldpointer)

My pointer is changing to the loading while computation but it isnt coming back to the orignal arrow after the code stops executing. Here is my code
oldpointer = get(handles.figure1, 'pointer');
set(handles.figure1, 'pointer', 'watch')
drawnow;
%code that runs
set(handles.figure1, 'pointer', oldpointer)

How can I use this in app designer?
it's giving me error.
Error using matlab.ui.Figure/set
Functionality not supported with figures created with the uifigure function. For more information, see Graphics Support in App Designer.

isn't handles a GUIDE only graphics structure. For APP designer it should be App.Figure1.

Users that looked for a waitbar style solution should have a look at https://de.mathworks.com/help/matlab/ref/uiprogressdlg.html which is basically waitbar but with an up to date look.
