This program should widen the rectangle 'spring'
maxStep=70;
speed=0.05;
[posArray5]=get(handles.spring,'position');
for i=1:1:maxStep
posArray5(1)=posArray5(1)+1;
pause(speed);
set(handles.spring,'position',posArray5)
end
And I wonder what is the problem because it doesnt work Help will be much apprecieted.

Don't just say "it doesnt work", say WHAT isnt working. The code you posted should draw a rectangle that moves across the screen, not one that widens. Is that the problem? If so, you want to be setting posArray5(3), which is the width, not posArray5(1), which is the horizontal offset.
