Yahtzee in Matlab?

Im trying to make the game yahtzee in matlab. Im setting up an array with 0's and 1's in it, and the 1's will be the dice that I want to reroll. I havent had to much trouble, but I cant figure out how to incorporate the reroll aspect into it. Im using an if statement to generate new random numbers if theres a 1 in the array. If theres a zero then there will be no need to reroll those dice in that position. Could anyone offer some help for the reroll process. Much appreciated.

Why do it in a complicated way, using loops and if statements?

d = randi(6,[1 5])
d =
     4     1     6     6     5

rerolls = [1 2 5];

d(rerolls) = randi(6,[1 numel(rerolls)])
d =
     5     5     6     6     3

Note that IF rerolls is an empty vector, then nothing should change. Does that work here?

rerolls = [];
d(rerolls) = randi(6,[1 numel(rerolls)])
d =
     5     5     6     6     3

Yep.

You still need to decide which dice to re-roll, but that is your problem.
