let's say
A = [ 1 2; 1 2; 1 2]
A =
1 2
1 2
1 2
Any command that can I separate it into turn into
B =
1 2
1 2
1 2
C =
0 2
0 2
0 2
Thanks!!
-------------- I try to do it like this, but doesn't work
B = A(:,1)
B =
1
1
1

you dramatically changed what you wanted from this post in just a few minutes, so I'm not sure exactly what result you want now.

A = [ 1 2; 1 2; 1 2];
A(:,1) = zeros(size(A,1),1);
Or if you want to keep your original A
B = zeros(size(A));
B(:,2) = A(:,2);
