You cannot do that.
The closest you can get is to have button B set a variable in a place that the code in button A can reach, with that code checking the value periodically. For example,
Button B:
set(handles.buttonA, 'UserData', 'stop');
Button A:
set(handles.buttonA, 'Userdata', []);
while ....
curval = get(handles.buttonA, 'UserData');
if ~isempty(curval) && strcmp(curval, 'stop')

Hi I did your suggestion, but I can never stop routine on Pushbutton A. Shall I do something extra in PushburronB

In your GUI, set some user data to your GUI handle.
In your loop, check this data and break accordingly.
