Hi! I would like to create a string like "AA";"BB";"CC";"DD",and so on.
The idea is similar to this:
letters_str = string(mat2cell('A':'Z',1,ones(1,26)))';
I would simply like to double the letters in 'letters_str'.

Ran in:
str = string(char('AA' + repmat((0:25)',1,2)))
str = 26×1 string array
"AA" "BB" "CC" "DD" "EE" "FF" "GG" "HH" "II" "JJ" "KK" "LL" "MM" "NN" "OO" "PP" "QQ" "RR" "SS" "TT" "UU" "VV" "WW" "XX" "YY" "ZZ"

Another idea -
str = string(('A':'Z')');
str = join([str str],'')
str = 26×1 string array
"AA" "BB" "CC" "DD" "EE" "FF" "GG" "HH" "II" "JJ" "KK" "LL" "MM" "NN" "OO" "PP" "QQ" "RR" "SS" "TT" "UU" "VV" "WW" "XX" "YY" "ZZ"
