How can i seperate a string in all possible smaller ones without using for loops;.

For example if my string is a='ATGCA' , i want to make b={'AT', 'TG', 'GC', 'CA'}.( the length of the smaller strings is random, it may be three or four in this example.)

Answer 1

[Stephen23]

>> a = 'ATGCA';
>> n = 2;
>> x = hankel(1:n,n:numel(a)).';
>> b = num2cell(a(x),2)
b =
  'AT'
  'TG'
  'GC'
  'CA'
