The Attempt at a Solution



I have

deck = ['AH';'2H';'3H';'4H';'5H';'6H';'7H';'8H';'9H';'TH';'JH';'QH';'KH';
'AS';'2S';'3S';'4S';'5S';'6S';'7S';'8S';'9S';'TS';'JS';'QS';'KS';
'AD';'2D';'3D';'4D';'5D';'6D';'7D';'8D';'9D';'TD';'JD';'QD';'KD';
'AC';'2C';'3C';'4C';'5C';'6C';'7C';'8C';'9C';'TC';'JC';'QC';'KC'];

but how do i get a random subset of 2 cards from this matrix??

try

Code: 
rnum = round(n*rand(1,2));
card1 = deck(rnum(1));
card2 = deck(rnum(2));

Where n is the number of cards you want to sample.
 
thanks that helps

so now i have:

Code: 
h1 = round(12*rand(1,2))+1;
disp(['Dealer deals you: ' , num2str(h1) ] )
d1 = input('hit or pass? ');
for hit
    h2 = round(12*rand(1))+1; % user's new hand
    h12 = [h1 h2];
    disp(['Dealer deals... you get: ' , num2str(h12) ]) 
end

i have round(12*rand(1,2))+1 because round(13*rand(1,2)) gives me a zero sometimes.
what's wrong with my for loop? when i type hit for input, i get an error
 
Your for loop was developed incorrectly it should read:

Code: 
for j=1:hit
    h2 = round(12*rand(1))+1; % user's new hand
    h12 = [h1 h2];
    disp(['Dealer deals... you get: ' , num2str(h12) ]) 
end
