Im having issues with removing values that can be inputted by the user in my matlab program. I have 6 randomly generated vales show up and im supposed to be able to remove any matching set of numbers from the array however im having issues getting these numbers removed then displaying the updated array again. Is there any way you can help? Any help would be appreciated.

This is what I have so far:

clear 
clc
rng('shuffle')
disp('Welcome to Farkle!');
NumberOfTurns=1;
fprintf('NumberOfTurns:')
fprintf('%4.0i\n',NumberOfTurns)
TurnScore=1;
fprintf('TurnNumber:')
fprintf('%4.0i\n',TurnScore')
GameScore=0;
fprintf('GameScore:')
fprintf('%4.0i\n',GameScore)
NumberOfDice=6;
fprintf('NumberOfDice:')
fprintf('%4.0i\n', NumberOfDice)
Roll=randi(6,1,6);
fprintf('Dice Values:\n')
fprintf('%6.0f\t',Roll)
fprintf('\n')
SortRoll=sort(Roll,'descend');
fprintf('Sorted Dice Values:\n')
fprintf('%6.0f\t',SortRoll) 
fprintf('\n')
%% Score Input
KeepScore=input('Enter the score of this roll:');
if KeepScore>0
    RoundScore=KeepScore;
    OverallScore=GameScore+RoundScore;
fprintf('Game Score:\n')
fprintf('%6.0\t',OverallScore)%Make sure to display gamescore number
KeepNumber=input('Enter the dice number that you wish to keep:');
SortRoll(KeepNumber)=[];

William - where in the above code do you want to remove duplicated values? From the

Roll=randi(6,1,6);

You could perhaps use unique...

yes my randi function generates 6 random numbers ( 1,3,3,5,2,3 for example) I need help removing certain values from the array (such as the number 1).
