How do I extract certain characters using for loop?

I need to extract 5 letters at a time from an input to go through a for loop. Such as if the input was 15 letters, how do I run the first five, next five, and last five at a time through for loop?

You define the loop index to increase by 5, instead of by 1.

a = 'ABCDEFGHIJKLMNO';

for i = 1:5:length(a)
  b = a(i:i+4);
  disp(b);
end
