Im trying to make yahtzee in matlab, and I understand how to do most of it. Im really struggling on the code for the rerolls. For instance if I roll once, and I want to keep dice 2 and 4, then how would I reroll only dice 1,3, and 5. I was thinking about using an array of 0's and 1's that would determine which dice I want to keep. True=0 and False=1. Appreciate any help, Thanks.

I think you'll have to give us some more information. What does your code look like? Your approach seems sensible; control your re-rolls with an indicator but without more information I don't know how we can help.

Is this a homework question? John answered this in http://www.mathworks.com/matlabcentral/answers/264706#answer_206976 and I also saw an answer from Walter here http://www.mathworks.com/matlabcentral/answers/264740#answer_207025

Perhaps if I rename some of his variables to something more descriptive:
% Get initial roll values of 5 dice.
diceValues = randi(6,[1 5])
% Define some indexes that you want to roll again.
diceIndexesToReRoll = [3,4,5];
% Assign the new values to those indexes only.
diceValues(diceIndexesToReRoll) = randi(6,[1 numel(diceIndexesToReRoll)])
Now it's up to you to figure out which dice to roll again and set the dice numbers in the variable "diceIndexesToReRoll" based on the rules of Yahtzee.

Can't be much more clear than that.
