Generate a sequence/vector of randomized letters

I would like to create a 1x10 row vector of randomized letters.

My code so far is:

    a='A':'Z';
    letters= a(randi(numel(a), 1, 10))

letters = 'FLNRJUMDZB'

I was wondering if I could have this sequence output in a way where each letter is spaced with a comma in between. Ex: Instead of 'ABCDE', I would like'A, B, C, D, E'. Thank you to whoever can help! (Note: I am quite new to MATLAB)

a='A':'Z';
letters= a(randi(numel(a), 1, 10))

letters = 'XMYNVGHUIL'

iwant = strjoin(cellstr(letters'),',')

iwant = 'X,M,Y,N,V,G,H,U,I,L'
