How to select a one random letter from a matrix of letters.

I have the array.

move = [R ,P, S]

How would I select a random letter from this array.

cmove = ?

Would it look something like this ?:

cmove = move(rand(numel(move)))

[Azzi Abdelmalek]

move = {'R' ,'P', 'S'}
cmove = move(randi(numel(move)))

or

move ='RPS'
cmove = move(randi(numel(move)))
