Converting Matrix to base b fails

the following code should create a multiplication table to the base b 
(now in the form of multTable(7,3:10,2:3:33), i know)
when calling the function like above i get an error thrown at "table(i,ii) = a;" 
Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 1-by-2.
I dont know why. when using table(i,ii) = 0; the programm runs perfectly.
I always thought that dec2base only returns one value thus making filling the matrix pretty easy.


function y = multTable(b, R, C)
    table = (R)' * (C);
    w = width(table);
    h = height(table);
    for i= 1:h
        for ii = 1:w
            a = dec2base(table(i,ii),b);
            disp(a);
            disp("**")
            table(i,ii) = a;
        end
    end
    y = table;
end

dec2base returns a character array representation that can be multiple characters:

dec2base(7,2) % "convert" decimal 7 to base 2

ans = '111'

thx for the answer ! i used str2num to finally get them into the matrix
