Quickly access a group of arrays using a loop

Hi,
I have a set of arrays labeled as "A1", "A2", "A3"..."An" What I would like to do is write a loop that allows me to access each without having to type the array names out individually. For instance if I wanted to access the first entry of each array:
for i=1:n A "i" (1) end
I've been messing with num2str and eval but I can't seem to get something that works. Any pointers would be appreciated.
Cheers, David

Using num2str() and eval() should be able to do it. See this post for details. But it is highly recommended not to name variable as A1, A2, A3,... as you now see the problem.

Thanks Fangjun.
Out of interest I got it to work with:
for i=1:n
A{i}=eval[('A' num2str(i))];
A{i}(1)
end
Cheers,
David
