What does this mean?

I defined a Cell array as following

C =

    'one'    'two'    'three'
    [  1]    [  2]    [   45]

Change 1: Changed the values of the 2nd row as follows >> C(2,:)={{1,2},{3,4},{5,6}}

and Got

C =

    'one'         'two'         'three'   
    {1x2 cell}    {1x2 cell}    {1x2 cell}

Change 2: if I changed the values as the following

>> C(2,:)={[1,2],[3,4],[5,6]}

C =

    'one'           'two'           'three'     
    [1x2 double]    [1x2 double]    [1x2 double]

Can someone please explain what is the difference between the results of change 1 and change 2?

Thanks a lot in advance

Change 1:

Each element of the 2nd row is a cell array. And each of those cell arrays has two elements (1x2 dimension). Each of those two elements is in and of itself a MATLAB double variable. The way you have constructed it, you have six separate double variables, [1], [2], [3], [4], [5], [6], that are stored inside of three cell arrays that are themselves stored inside of a single cell array.

Change 2:

Each element of the 2nd row is a double array. And each of those doubles arrays has two elements (1x2 dimension). The way you have constructed it, you have three separate double variables (each 1x2), [1 2], [3 4], [5 6], that are stored inside of a single cell array.
