The string 'Hello' consists of single characters already:
str = 'Hello';
for k = 1:length(str)
disp(str(k))
end
So please explain the wanted type and dimensions of the output. 'H' 'E' 'L' 'L' 'O' is not clear enough.

Try num2cell, e.g. where W is your word (a 1xN character vector):
C = num2cell(W(:))

num2cell is the best solution. In case str is of class string
c = num2cell(char(str));
This works when str is a character array or a string.

E
>> str(3)
L
