How to set up dynamic naming of vectors?

LETS SAY:

I have a large matrix of unknown size in a text file.

I wish to import it column by column and store each column as a vector.

I wish to name the vectors something like data1,data2,data3,...etc.

================

QUESTION:

How to dynamically name vectors I am creating?

I obviously need to use a loop but how do I set a naming condition?

 Z = dlmread('file.txt') %import file in to matrix Z
 a = length(Z(1,:))      %acquire number of columns

 for N = 1:a
     'data+N' = Z(:,N)   %obviously wrong but how do I make matlab understand?
 end

THANK YOU!

Think I got it to work, thanks!

 %A is a 2x10 matrix

 for i=1:10
   B{i} = A(:,i); %trying to get B{1}=A(:,1) B{2}=A(:,2) ETC
 end

I think Walter's point is that you should definitely be using eval().

Either that, or that what you think you want to do is the last thing that you should really be doing.

B{i} rather than B(i)

Also for this kind of splitting use mat2cell()

Well I got it to work so I think I am good but in response to your comment I do want to mention the guide he linked condemns using EVAL :)

"Repeat: don't create variables at runtime using EVAL unless you have a very good reason, such as someone gives you a MAT file with 2000 variables named A1428, for example. Even in that case, you can avoid EVAL"

Nathaniel was poking fun at me ;-)
