Concatenate More than 2 Variables

Can Matlab handle concatenation of more than 2 variables?

eg.

A{1}=[1 2 3]
A{2}=[4 5 6]

I understand that C=vertcat(A{1},A{2}).

However, if I have say 100 variables and I wish to vertcat them, how can I do so?

eg.

A{1}=[1 2 3]
A{2}=[4 5 6]
A{3}=[7 8 9]
A{4}=[10 11 12]

and so on....until A{30}.

How can I do so with a single function?

Found it.

C=vertcat(A{:})

Or,

 C=cell2mat(A);

cell2mat only converts Cell to Double. It doesn't concatenate.

[Walter Roberson]

Actually it does concatenate.
