Create a matrix where the same row has been duplicated vertically up to a certain number

I'm trying to duplicate a row Xavg that is collected from another function called avg. When I use

   disp (Xavg);  % I can see that the system fetches the correct row.

Now I want to make a new matrix where I have duplicated this row a certain number of times vertically, which in my code I refer to as mX.

Also size from the matrix X is fetched correctly, where mX equals 10 rows.

Here is my code:

 [mX nX] = size(X);

    XXI = [];
    XXII = [];
    Xavg = avg(X);

    for i = 1:mX
        XXII = [XXI;Xavg];
    end

    disp (XXII );

Now the end result shows the row from Xavg, but only once, in other words it just shows the same rowvector unmodified and not the matrix I wished to get with the same rows duplicated vertically. Can anyone spot the error in my code?

XXII=repmat(Xavg,mX,1)

That really worked out exactly as wished, good to know, thx a lot!
