@Joseph Kutteh this question doesn't differ much from the question you asked earlier this week and never replied to:
how to have a callback function terminate another callback function in a GUIDE gui
And it's no surprise that both questions describe the same solution with some minor differences.

% Initialize in the CreateFcn: handles.Pause = false
function pushbutton1_Callback(hObject, eventdata, handles)
handles.Pause = (hObject.Value == 0);
guidata(hObject, handles);
end
function pushbutton2_Callback(hObject, eventdata, handles)
for k = 1:1000
disp(clock); % <-- This is the pseudo code
pause(0.5); % <-- Insert your real computations instead
% If button1 was pressed, stay in this loop:
while handles.Pause % [EDITED] WHILE instead of IF ?!
handles = guidata(hObject);
pause(0.2);
end
end
end

I do not understand, what you are asking for. I've marked the dummy lines now, which I have inserted instead of the real computations.

The while loop in Jan's answer 'pauses' execution if the pause-flag is set to true. This flag is set by pressing pushbutton1 which must be a togglebutton that has a binary state (on/off) (see the pushbutton1_Callback function in Jan's answer).
Note that execution isn't really paused. It's just stuck in the while loop until it gets the signal to escape.
Before you sink too much time into a GUI that appears to be created by GUIDE, note that,
>The GUIDE environment will be removed in a future release. After GUIDE is removed, existing GUIDE apps will continue to run in MATLAB® but they will not be editable in GUIDE - noted in r2021 documentation.
Other ways to implement pauses in Apps/GUIs.
  • waitfor - example using AppDesigner but can be implemented outside of AppDesigner, too.
  • uiprogressdlg with the Indeterminate option (requires uifigure which excludes GUIDE GUIs)
