MatLab Code, requires more arguments to run

why wont this code run?

function [winner,playerscore] = goFish2(h1,h2,deck)
 
playerscore(1)=0;
 
playerscore(2)=0;
 
for i = 1:(length(h1)-1)
    if(h1(i)==h1(i+1))
 
        playerscore(1) = playerscore(1)+1;
 
        h1(i)=[];
 
        h1(i)=[];   
 
        if(i+2>length(h1))
            
 
            break;
 
        end   
 
    end
 
end
 
for i = 1:length(h2)-1
 
    if(h2(i)==h2(i+1))
 
        playerscore(2) = playerscore(2)+1;
 
        h2(i)=[];
 
        h2(i)=[];
 
        if(i+2>length(h2))
 
            break;
 
        end
 
    end
    while(isempty(h1) && ~isempty(h2))
 
       if(h1(1)==h2(1))
 
        h1 = h1(2:end);
 
        h2 = h2(2:end);
 
        score(1) = score(1) + 1;
 
     else
 
        if(~isempty(deck) && h1(1)==deck(1))
 
            h1 = h1(2:end);
 
            deck = deck(2:end);
 
            score(1) = score(1) + 1;
 
        else
 
            if(~isempty(deck))
 
                temp = h1(1);

        break;
 
    end

        playerscore(2) = playerscore(2) + 1;
 
    else

How are you trying to run it?

[Nick Olibrice]

I wasnt using the correct input for the command window so it was not working, I think I got it now. I have been trying to make a functional game of goFish in MatLab.

Nevermind, I am unaware how to run this script, it does not work. I am trying to do what I said in my previous comment.

Thank you.
