Assign a Sub Array to Array Knowing the Number of Dimensions at Run Time

Assume we have tA and tB with the same number of dimesions. We also have all(size(tB) <= size(tA)) == true.
The task is to embed tB in tA. Something like: tA(1:size(tB, 1), 1:size(tB, 2), ..., 1:size(tB, n)) = tB. Yet since we know the number of dimensions only at runtime, it can't be written explicitly like that.
The question, is there an efficient way to do so without eval or explicitly computer the cartesian product and use sub2ind()?

There is probably a better way, but you can fill a cell array with the index vectors (simple loop with ndims), and then use this:
tA(inds{:}) = tB;
