To concatenate horizontally the content of a cell array we can use the very practice syntax [C{:}]. For example:
A = {(1:3) (4:7)};
B = [A{:}]
B =
1 2 3 4 5 6 7
Is there a way to obtain the same results in the vertical direction (except vertcat of course)
A = {(1:3)' (4:7)'};
B = ?
B =
1
2
3
4
5
6
7

Well, it's not vertcat...
B=cat(1,A{:})
But no, I don't think there's a way purely with operator syntax.

Correct, there is no operator syntax for this.

This won't work if, as I did on purpose in the example, the vectors inside C are not all the same length.
Moreover, even if the are, the result is not the wanted one.

"except vertcat of course"
Thank you, but as [C{:}] is an equivalent for horzcat(C{:}), I was asking myself if there was such an equivalent for vertcat too..

Do exactly the same thing, then transpose B...
A = {(1:3) (4:7)}; B = [A{:}]'

This only works when the elements of A are row vectors, not column vectors, as in the OP's example.
