You can write your flag in the UserData-property of the toolbaricon.
...
set(handles.uitoolbar1,'UserData',0)
for ...
if get(handles.uitoolbar1,'UserData')
break
end
end
...
function uipushtool1_ClickedCallback(hObject, eventdata, handles)
set(handles.uitoolbar1,'UserData',1)

set(handles.uitoolbar1,'UserData',0)
for i=1:1:inf
if get(handles.uitoolbar1,'UserData')
break
end
a=i
pause(0.00000000000000000000001)
end
If I put pause ,,then only its working,,,

The tiny interval for PAUSE is not useful. Use pause to get the shortest possible delay. Usually drawnow is used to allow ui-objects to update.

Each function has its own workspace, such that a variable set in one function is not visible in the other. A solution is to set a flag e.g. in the UserData of a figure or any other UI-object. This flag can be checked from inside the loop also.
