Subscript indices must either be real positive integers or logicals.

Hi,
dist = sqrt((r1 - r2) ^ 2 + (c1 - c2) ^ 2);
costs(i) = 1 /ceil( dist) * exp(- abs(ceil(img(abs(r1), abs(c1))) - ceil(img(abs(r2),abs(c2)))) ^ 2 / (2 * sigma ^ 2));
c2 is equal to 0 ,so it returns Subscript indices must either be real positive integers or logicals.
Thanks

If c2 is zero, img(abs(r2), 0) won't work. Make sure it's not zero.

Check if abs is not used as a variable in your code. You can check by writing
whos abs
You can resolve the problem by typing
clear abs
abs(c2)
