Hi,
I am interested in asking the user to continue the code execution.
If he enters 'Y', it should make the code to run again from the start. Otherwise for 'N' it should stop.
I think, it will start with something like this:
m=input('Do you want to continue, Y/N [Y]:','s')
Please help
Thanks

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

You also can create a dummy variable and set it to zero in the 'if' statement:
x=1;
while(x)
if ...
x=0;
end
end

Thank you so much for this. I was having problems with accidentally overwriting exported figures so now I have adapted this so it asks me if I want to export the figure or not, saves a lot of hassle as I always forget to comment it out when I just want to test run the formatting of the figure first.
