From variable name to data

Hello buddies, I got a problem that has frustrated me for about 10 hours today.

I defined 3 variables with names:

v{:,1:3} = genvarname(['v ' label{1,1:3}])
eval([v{:,1:3} '= data(1:nrRows,1:3);'])

This gives v that contains x1 x2 and x3. Each x's has 100 rows.

My problem is, that I would like, somehow(?), to write something like:

v(:,1) or v(:,2) or v(:,3) to optain all 100 rows, in each v(:,i)..

But if I write e.g. v(:,1) I get this answer: 'x1'.. (I can't convert it to numbers (100 rows with data)).

Im sorry if this is very trivial, - I dont program in Matlab everyday.

Hope to hear from someone, have a good day

best

Mergh

Thanks for both your answers! I will look at it today from now, and get back when I (hopefully) find a solution
