Take the example of code pasted below.
I just want that the ball move back and forth again and again until some body closes the figure. I used 'while true' loop but it is not useful in this regard.
x = linspace(-1, 1, 75);
y = -x.^2;
figure(1)
for k2 = 1:2
for k1 = 1:length(x)
plot(x(k1)*(-1)^k2, y(k1), 'ob', 'MarkerFaceColor','r')
axis([min(x) max(x) min(y) max(y)])
refreshdata
drawnow
end
end

Define a figure CloseRequestFcn like below
function my_closereq(src, callbackdata)
selection = questdlg('Close This Figure?',...
'Close Request Function',...
'Yes','No','Yes');
switch selection
case 'Yes'
delete(gcf);
case 'No'
return
end
end
And use this script
x = linspace(-1, 1, 75);
y = -x.^2;
fig = figure('CloseRequestFcn', @my_closereq);
ax = axes(fig);
while true
for k2 = 1:2
for k1 = 1:length(x)
plot(ax, x(k1)*(-1)^k2, y(k1), 'ob', 'MarkerFaceColor','r')
axis([min(x) max(x) min(y) max(y)])
refreshdata
drawnow
end
end
end
Hope this helps!
