Poker game simulator (texas holdem)

i am trying to simulate a poker game to become more familiar with matlab as i am fairly new. So far i have written code to generate the deck, and calculate the best hand a player can make out of the 2 hole cards and the 5 community cards. I now want to simulate the actual game:

• players post big blind/small blind/ante
• round of betting preflop
• round of betting on the flop, turn, and river
• players reveal thier cards and the best hand wins (i can use my hand rankings to do this)

i am unsure as to the methodology i could use to begin this, how do i tell matlab that a player can bet, check, call, or fold when the action is on the player? Any help greatly appreciated.

This question seems like a duplicate to the question present in here.

[philip curran]

this question focusses more on how the deck is organised within MATLAB, i was more curious about how betting/folding/checking would work within MATLAB. (given that there are very high number of possibilities of how the action can go in a single hand of poker)

heres what i've gotten up to so far:

i made use of a function from the MATLAB file exchange in order to rank the hands: Poker hand ranker - File Exchange - MATLAB Central (mathworks.com)

BB = 1;
SB = 0.5;

if round == 1 % preflop
    if position == 1 % SB post blind
        p1_chips = p1_chips - SB;
        p2_chips = p2_chips - BB;
        pot = [SB + BB];
    elseif position == 2 % BB post blind
        p1_chips = p1_chips - BB;
        p2_chips = p2_chips - SB;
        pot = [SB + BB];
    end

    holecard1 = deck(1);  % deal hole cards
    holecard2 = deck(2);
    hand1 = [holecard1,holecard2];
    [ranks,descriptions,usedcards,unusedcards] = rankp(hand1); % determine card ranking
    
    prompt = "What action would you like to take "; % asks user to input action: check, bet, or fold. (i think i can someway connect this input to the action if statements)
    action = input(prompt,"s")

elseif round == 2 % flop
    holecard1 = deck(1);  
    holecard2 = deck(2);
    flop1 = deck(3); % deal flop
    flop2 = deck(4);
    flop3 = deck(5);
    hand2 = [holecard1,holecard2,flop1,flop2,flop3];
    [ranks,descriptions,usedcards,unusedcards] = rankp(hand2); 

    action = [];

    prompt = "What action would you like to take "; 
    action1 = input(prompt)

elseif round == 3 % turn
    holecard1 = deck(1);  
    holecard2 = deck(2);
    flop1 = deck(3); 
    flop2 = deck(4);
    flop3 = deck(5);
    turn = deck(6); % deal turn
    hand3 = [holecard1,holecard2,flop1,flop2,flop3,turn];
    [ranks,descriptions,usedcards,unusedcards] = rankp(hand3); 

    prompt = "What action would you like to take "; 
    action = input(prompt,"s")

elseif round == 4 % river
    holecard1 = deck(1);  
    holecard2 = deck(2);
    flop1 = deck(3); 
    flop2 = deck(4);
    flop3 = deck(5);
    turn = deck(6);
    river = deck(7); % deal river 

    hand4 = [holecard1,holecard2,flop1,flop2,flop3,turn,river];
    [ranks,descriptions,usedcards,unusedcards] = rankp(hand4); 

    prompt = "What action would you like to take "; 
    action = input(prompt,"s")

elseif round == 5
    disp('showdown!!!!')
    p1_hand = [deck(1),deck(2),deck(3),deck(4),deck(5),deck(6),deck(7)] 
    [ranks,descriptions,usedcards,unusedcards] = rankp(p1_hand);        % determines hand rank of player 1
    p1_rank = ranks;

    p2_hand = [deck(8),deck(9),deck(3),deck(4),deck(5),deck(6),deck(7)] 
    [ranks,descriptions,usedcards,unusedcards] = rankp(p2_hand);        % determines hand rank of player 2
    p2_rank = ranks;

    if p1_rank > p2_rank
        disp('p1 wins')
        p1_chips = p1_chips + pot;        
    elseif p2_rank > p1_rank
        disp('p2 wins')
        p2_chips = p2_chips + pot;
    end

    disp('move onto next hand') % not sure how to make this reset

end
