How to display results in vertical table format

I'm writing a simple annual compound interest problem, the results are being displayed horizontally. How do I display it horizontally? below is the code.

    % M-file to calculate ANNUAL Compounded Interest
    % user specified values
    % Amount of money = P
    % Yield is the account total = F
    % interest rate (decimal) = i
    % number of years to calculate account total = n

    display('Compound interest Formula')

    P = input('Enter initial principal:');
    i = input('Enter Interest rate as decimal (ex: 2% = 0.02 and 12% = 0.12): ');
    t = input('Enter number of years to calculate total investment:');

    disp(' Years        Yield');

    for k = 0:t;
        F = P*(1 + i).^(k); 
        out = [k F];
        fprintf('%5d %12.2f\t', out);
    end
