Cyclist is right, but I'd still like to give it a shot base on your question. Assuming all parameters are numbers, say you have 5 parameters for each player, with a total of 10 players.
statsheet = [magic(5),magic(5)];
You can simply obtian the correlation coefficient between each player with the following.
preferablyPercentageCorrelated = r.^2;
'preferablyPercentageCorrelated' will be the "preferably percentage correlated" values between each player.
