x=0:0.5:2*pi;

y=sin(x);

h=plot(x,y);

grid on

hm=uicontrol(gcf,'style','popupmenu',...

'string',...

'sin(x)|cos(x)|sin(x)+cos(x)|exp(-sin(x))',...

'position',[250 20 50 20]);

set(hm,'value',1)

huidiao=[...

'v=get(hm,''value'');,',...

'switch v,',...

'case 1,',...

'delete(h),',...

'y=sin(x);,',...

'h=plot(x,y);,',...

'grid on,',...

'case 2,',...
