KSSV is right :v it's basically the same goddamn question :w ... Code:

function[] = someonesHW_2()
idx=1;
prompt='Enter a number: ';
while true
  inp=input(prompt,'s');
  if inp=="done"
      break;
  elseif isstring(inp)==1 && inp~="done"
      disp('Invalid input!')
      continue
  else
      a=str2double(inp);
      A(idx)=a;
      idx=idx+1;
  end
end
Sum=sum(A(:));
Ave=Sum/(idx-1);
disp(['Total = ',num2str(Sum),'; count = ',num2str(idx),'; average = ',num2str(Ave)]);
end%someonesHW_2()
