Combining matrix of different dimension.

I have three matrix. Matrix 1 = [2 2; 0 0],Matrix 2 =[1 1;0 0] and Matrix 3=[2 2 2 2 ;3 3 3 3] . I will like to combine these 3 matrix such that it becomes [2 2 0 0;0 0 0 0;1 1 0 0;0 0 0 0;2 2 2 2;3 3 3 3]. Appreciate your kind assistance. Thanks.

m1 = [2 2; 0 0];
m2 =[1 1;0 0];
m3=[2 2 2 2 ;3 3 3 3];

C = {m1,m2,m3};

[r,c] = cellfun(@size,C);
m = max([r(:),c(:)]);
for ii = 1:numel(C)
    if any([r(ii),c(ii)] < m)
        C{ii}(m(1),m(2)) = 0;
    end
end
out = cat(1,C{:})

One solution:

Matrix1 = [ 2 2; 0 0];
Matrix2 = [1 1;0 0];
Matrix3 = [2 2 2 2;3 3 3 3];

[reshape(Matrix1',1,4);zeros(1,4);reshape(Matrix2',1,4);zeros(1,4);Matrix3]
