for example: if I have: "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA", I want to split it into lines after 4 characters and then I could have:"AAAA" "AAAA" "AAAA" "AAAA"

This divides them into 8 rather than 4 strings:
str = 'AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA';
SplitLen = 4;
CheckLen = SplitLen*fix(length(str)/SplitLen); % So ‘reshape’ Will Work
Result = {reshape(str(1:CheckLen), [], 4)}; % Result As Cell Array

still it does not work, because if the length of remainder of string is less than what was defined it will be ignored and i don't want this

The string argument to reshape has to be an integer multiple of the desired length of the substrings. The easiest way to deal with the remainder of the string is to append it to the end:
Result = {reshape(str(1:CheckLen), [], SplitLen); str(CheckLen+1:end)};

s=reshape(s,L,[]);
Requires rem(length(S)/L)=0, of course.
