Hello,
I am playing a video inside a for loop (for frame = startframe:endframe) and the image updates for each iteration in the for loop.
I want the user to be able to move forward and backward inside the loop depending on which button is pressed. Say "left arrow key" moves to previous iteration and "right arrow key" moves to next iteration.
How can I do this?
Thanks!

%Right
for i = 1:10
fprintf('%d\n',i)
end
1 2 3 4 5 6 7 8 9 10
% Left
for i = 10:-1:1
fprintf('%d\n',i)
end
10 9 8 7 6 5 4 3 2 1

How would I change within the loop. Let's say I am at index 40 in my loop and now I want to go left 39,38,37 now I want to go right again 38,39,40, etc.
Can you show an example?
Thanks.
