Trying to learn Rand - help get me started

Hi, I'm trying to learn Matlab so I be more useful as an intern. Looking through the book I bought theres some practice - i have trouble with the following one, which is a "try this" problem and do they don't actually tell you how to do it:

Use an Array of characters 'A234567890JQK' to display a single random playing card. Hint: use a random number as an index value. Note that A = ace, 0 = 10, J = jack, Q = queen, and K = king. In oter words, your expression should randomly display a single character in the array.

So far I know how to put numbers in arrays, but characters? Can someone explain a way how to do so?

Thanks

>> arrayOfAllCardRanks = 'A234567890JQK'

defines an array of characters, of size 1x13

I suggest using the randi() function for your next step, but won't give you the details.
