Set the infinite loop. I did not check if this code runs, but the idea is this:
while(1)
%%your code here
m=input('Do you want to continue, Y/N [Y]:','s')
if m=='N'
break
end
end
Also, to avoid check up for extra cases from user input I would use function 'menu' instead of 'input':
while(1)
%%your code here
choice = menu('Press yes no','Yes','No');
if choice==2 | choice==0
break;
end
end
