graph - matlab shape object if function -

i want create object move in matlab. code of next nature

global stop stop = 0; frame=1:1:length(t) if stop ~= 1 axes(handles.aaxes) cla hold on if y(frame)<=0 rectangle('position',[3,1,3,(0.000001)],'facecolor','b'); else rectangle('position',[3,1,3,((y(frame)+0.00000001))],'facecolor','b'); end hold off axes(handles.graph) cla hold on plot(t,y) plot(t(frame),y(frame),'*k') end % ff(f)=getframe; % f=f+1; end

this makes rectangle move upwards continuously until settles height (position y) graphical user interface. want rectangle move downwards instead of upwards (and hence settle position y). possible somehow?
