ind2sub output dimension

My question is regarding the output of the ind2sub function. In my code, since the input dimention of ind2sub changes, i should expect the output dimention to change. But a code like this is not working.
B = rand(6,6,6);
A(1:ndims(B)) = ind2sub(size(B),56);
The output of the above code is [56 56 56] while I'm expecting something like [2 4 2].
Any suggestion?

Follow the same clue in the answer to your other question, you can do the following:
Sub =
[6x1 double] [6x1 double] [6x1 double]
SubMatrix =
4 5 1
1 1 2
2 1 2
3 1 2
4 1 2
1 2 2

But as I've mentioned, the output dimention is changing. So I do not know if the I need three variables, in your case r, c, p, of if I need more.
