How can I compare the ranks of 2 random cards from a deck in matlab

Say I have 2 cards '7D' and 'JC' 7 of diamond and jack of clubs. How do I tell matlab to compare and print a certain result when one is greater than the other and print results for when one is ranked lower?

[~, rank1] = ismember(cardname1(1:end-1), {'2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A'});
[~, rank2] = ismember(cardname2(1:end-1), {'2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A'});

if rank1 > rank2
   disp('certain result')
elseif rank1 < rank2
   disp('results')
else
   cards are equal. Guess we should crash
end

should I replace cardname1 and 2 with the card strings?

[Walter Roberson]

You should replace cardname1 with the variable that holds the card strings, since it is very unlikely that you are wanting to do this for fixed card strings.

For example

FirstCard = '7D';
SecondCard = 'JC';

[~, rank1] = ismember(FirstCard(1:end-1), {'2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A'});
[~, rank2] = ismember(SecondCard(1:end-1), {'2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A'});
