MonteCarlo Simulation Roulette script/function

I already have a function that works for the Simulation of a Roulette and now i want to create a script to ask the Player(User) to choose a colour and his bet amount.

I tried to put the function in my script but the payout for the bet is not right, when i put the function in the script. But the function works and i get the payout.

When i choose for example red in input and 100 Euro for bet amount and i win then the payout is not right. If i win then the payout should be 200 Euro but here it is 106 and 96 Euro.

ans =

"rot"

106 96

My Script:

colour = input('Choose red,black or green ','s');

bet = input('choose bet: ','s');


while isnan(str2double(bet)) == true 
    bet = input('error.again please ','s');  
end



disp(montecarlos(colour, bet))



function payout = montecarlos(colour, bet)

red   = [3 12 7 18 9 14 1 16 5 23 30 36 27 34 25 21 19 32];
black = [26 35 28 29 22 31 20 33 24 10 8 11 13 6 17 2 4 15];
green = [38];


roulette = randi(38);

validatestring(colour,["red", "black", "green"])

if colour == "red" && any(roulette == red)
         payout = 2*bet;
elseif colour == "black" && any(roulette == black)
         payout = 2*bet;

elseif colour == "green" && any(roulette == green)
         payout = 2*bet;

else % loose
         payout = 0;
end

end

You should use strcmp to compare the contents of strings and chars.

Also, where exactly are you converting your bet to a numeric value?

bet='50';
payout=bet*2

payout = 1×2

106 96

Do not use 's' option in input():

bet = input('Specify the amount of your bet: ');
