Subtraction of a constant from a matrix column

Hi all, I'm trying to subtract a constant from every element in a matrix column, as the title suggests. The code I have is the following, however it does not work:

ver(:,1) = ver(:,1)-X;

Example. If we take ver = [1 2 3 ; 4 5 6], and X=3. So what I want to get by this subtraction is ver = [-2 2 3 ; 1 5 6].

Any help is appreciated. Thanks in advance! Cheers!

It works for me

>> ver = [1 2 3 ; 4 5 6]
X = 3

ver =

       1     2     3
       4     5     6

X =

       3

>> ver(:,1) = ver(:,1)-X

ver =

      -2     2     3
       1     5     6

What do you mean by it doesn't work?
