How do I avoid a nested loop when assigning vales to a multidimensional structure in MATLAB 7.4 (R2007a)?

I have created a 2x4 structure and a 2x4 matrix like this:

s = repmat(struct('a', 0), 2, 4);

xx = [11 12 13 14;21 22 23 24];

Now I want to assign s(i,j).a = xx(i,j), and I would like to do it vectorized not with a nested loop like this:

for i = 1:2

    for j = 1:4

      s(i,j).a = xx(i,j);

    end

end

By using the functions MAT2CELL, CELL2STRUCT and RESHAPE you can avoid using a nested loop when assigning values to the multidimensional structure.

s1 = repmat(struct('a', 0), 2, 4);

xx = [11 12 13 14;21 22 23 24];

c=mat2cell(xx(:),ones(numel(xx),1),1)

s2=cell2struct(c,'a',2)

s3=reshape(s2,size(xx))
