Generating 80 random alphabet letters in matlab-CodePudding

I have to generate 80 random letters of the English alphabet (capital letters) and display them in a row of 10 letters per row. I have a similar code for bingo numbers but I'm not sure what to change to adapt it for the alphabet

bingo = 1 : 99; 
for i = 1 : 99
temp = bingo(i); 
swop = floor(rand * 99   1); 
bingo(i) = bingo(swop); 
bingo(swop) = temp;
end
for i = 1 : 10 : 81
disp(bingo(i : i   9))
end
disp(bingo(91 : 99))

How do I adapt it for the alphabet?

>> letters = ‘A’:’Z’;
>> letters(randi(26, 8, 10))

ans =
