Flipped numbers (number pyramid)

% Please help on how can I do a flipped pyramid of integers from 1-9.
% I have this code
n = 4;
for k = 1:n;
        for c = 1:n-k;
            fprintf(' ');
        end
        for c = 1:n
            fprintf('%d', 1:k);
        end
        fprintf('\n');
end

However, this code outputs:

1111

12121212

123123123123

1234123412341234

An integer must be inputted and then this number must also correspond to the number of rows that is printed in the command window, along with the increasing numbers up to the inputted number. For example, if I input 4, the output should be this.

12

123

1234
