Identify flop hand categories in poker (combinatorics using cell arrays)

I guess that others have done it before me, but I would like to learn it from scratch anyway (I cannot find any tutorial or tips/tricks anywhere though).

Say we are given the hand range:

handrange={'AA','KK','AKs','QQ','AKo'};

pokerterms where s stands for suited and o denotes offsuit. Each pair ('AA', 'KK', and 'QQ') has 6 variations (heart/club, heart/diamond, heart/spade, club/diamond, club/spade, diamond/spade) and nonpairs ('AK' which consists of 'AKs' and 'AKo') have 16 combinations of which 12 are offsuit and 4 are suited.

The flop cards:

Ace [club] King [heart] 3 [heart], i.e.:

flop={'Ac','Kh','3h'};

in a no limit texas holdem game.

How do we, given the handrange and flop cards, actually identify the various categories: pair, straight draws, flush draws, and so forth?

pokerterms For a straight and flush draw, one card is missing to make the hand. A straight is a hand that contains five cards in sequence e.g. 5 [heart], 6 [club], 7 [spade], 8 [spade]). A flush is a hand that contains five cards all of the same suit e.g. Ace [heart], Jack [heart], 9 [heart], 3 [heart] and 2 [heart].

I guess one needs to compare strings in some kind of way?
