MATLAB: How to play many rounds in Rock, Paper and Scissors game

for looppaperrock

Hi,
I have a script to simulate this classic game. The question is: How can I play many rounds? I was thinking that was using for loop, but I could not find the correct way to accomplish that.
Here the script without repetition:
 disp('Stone, Paper and Scissors')
disp('Stone      (1)')
disp('Paper      (2)')
disp('Scissors   (3)')
n=input('Which choice?: ')
pc=[1,2,3];
switch(n)
    case 1
        MATChoice=datasample(pc,1)
        if c1==1
            return
        end
        if MATChoice==2
            display('MATLAB win; Player LOSE')
            return
        end
        if MATChoice==3
            display('MATLAB lose; Player WIN')
            return
        end
    case 2
        MATChoice=datasample(pc,1)
        if MATChoice==1
            disp('MATLAB lose; Player WIN')
            return
        end
        if MATChoice==2
            return
        end
        if MATChoice==3
            disp('MATLAB win; Player LOSE')
            return
        end
    case 3
        MATChoice=datasample(pc,1)
        if MATChoice==1
            disp('MATLAB win; Player LOSE')
            return
        end
        if MATChoice==2
            disp('MATLAB lose; Player WIN')
            return
        end
        if MATChoice==3
            return
        end
    otherwise
       error('Choose 1,2 or 3')
       return
end
return
end
Could you help me, please?
Thank you.

Try this:
numberOfTrials = 30; % Whatever you want...
for k = 1 : numberOfTrials
  choices = {'Rock', 'Paper', 'Scissors', 'Quit'};
  userChoice = menu('Which choice?: ', choices)
  if userChoice == 4
    break;
  end
  computerChoice =randi([1,3])
  message = sprintf('You chose %s and computer chose %s', ...
    choices{userChoice}, choices{computerChoice})
  switch userChoice
    case 1
      switch computerChoice
        case 1
          message = sprintf('%s\nTie', message);
        case 2
          message = sprintf('%s\nComputer wins.', message);
        case 3
          message = sprintf('%s\nYou win', message);
      end
    case 2
      switch computerChoice
        case 1
          message = sprintf('%s\nYou win!', message);
        case 2
          message = sprintf('%s\nTie', message);
        case 3
          message = sprintf('%s\nComputer wins', message);
      end
    case 3
      switch computerChoice
        case 1
          message = sprintf('%s\nComputer wins.', message);
        case 2
          message = sprintf('%s\nYou win!', message);
        case 3
          message = sprintf('%s\nTie', message);
      end
    case 4
      break;
  end
  uiwait(helpdlg(message));
  
end
