How to create a cell arrays consisting of various combinations of letters ABCDE? Letters can be repeated.

What about the lengths of the strings? Are 'ABBD' and 'EEECBAABBEEEDDD' both allowed (in different cells of course)? Or so they all have to be 5 characters long, like 'AAAAA' and 'AECCB'?

Try this:

clc;
numberOfCells = 10; % Whatever you want
letters = cell(numberOfCells, 1); % Initialize.
for k = 1 : numberOfCells
  % Get random length between 1 and 9
  thisLength = randi(9);
  % Get all letters from A up to the max allowed.
  % Numbers are randomly chosen so that repeats may occur.
  m = 64+randi(thisLength, [1, thisLength]);
  letters{k} = sprintf('%c', m);
end
% Show the cell array in the command window.
celldisp(letters);

In the command window you'll see:

letters{1} =
DBBAGED
letters{2} =
ABC
letters{3} =
AA
letters{4} =
A
letters{5} =
DBCA
letters{6} =
ADDB
letters{7} =
CDFECCD
letters{8} =
BCCB
letters{9} =
AABB
letters{10} =
FFCBEE
