if(b~=1)
msgbox('ok');
end
if(b==1)
msgbox('false');

In function pushbutton1_Callback you should update your handles
handles.metricdata.a=1;
guidata(hObject,handles)

You did not Answer my question, have you updated your handles with guidata, also, have you initialized handles.metricdata.a in your opening function?

In your yourfilename_OpeningFcn
handles.metricdata.a=0;
guidata(hObject,handles)
In
function pushbutton1_Callback(hObject, eventdata, handles)
handles.metricdata.a=1;
guidata(hObject,handles)
In
function pushbutton2_Callback(hObject, eventdata, handles)
b=handles.metricdata.a;
