Storing unknown number of user inputs

Hello. I need help with the following. I want to store the user's inputs in an array to later perform operations on such numbers. I know you can't preallocate an array of unknown dimensions, so what do I do? What is wrong so far? Thx!!!

UserNumber = input('Enter a number:');
Total = UserNumber;
MultIn = zeros(x,1);
while UserNumber ~= 0
    UserNumber = input('Enter a number:');
    Total = UserNumber + Total;
    minTotal = min(Total);
    maxTotal = max(Total);
    meanTotal = mean(Total+UserNumber);
    prodTotal = UserNumber*UserNumber;
end 
fprintf ('Sum of your last inputs: %d\n', Total)
fprintf ('Minimum of your last inputs:%d\n', minTotal)
fprintf ('Maximum of your last inputs:%d\n', maxTotal)
fprintf ('Mean of your last inputs:%d\n', meanTotal)
fprintf ('Product of your last inputs:%d\n', prodTotal)

UserNumbers = []
Total = 0
Totals = []
Now loop fetching into UserNumber
   UserNumbers(end+1) = UserNumber
   Total = Total + UserNumber
   Totals(end+1) = Total
End the loop
min(Totals)
max(Totals)
mean(Totals)
prod(Totals)
min(UserNumbers)
max(UserNumbers)
mean(UserNumbers)
prod(UserNumbers)
