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.
