i am trying to create a loop to check for win conditions for either 1's or 2's. but when i attempt to create the code it either doesnt finish the code, or it become stuck in the loop i created.

Hi,
Assuming you want your code to end execution once the win condition is reached, you can use the return function as follows
if board(row + 3,col) == 1
fprintf('pcOne Wins');
return;
end
Additionally, for code getting stuck in the loop, you may want to verify that the variables used for checking the exit condition of the loop are being updated correctly.
Hope this helps
