MATLAB: How to remove the last column in the matrix

Question

Hello! There are matrices, I need to delete the last column, how would I do this?

A=[2 4 2 4 2 6 8];
[x,y]=size(A);
A(:, y) = [];

I try something like this, but I need to change the changed data to another array

Answer 1

>> A = [2,4,2,4,2,6,8]
A =
  2  4  2  4  2  6  8
>> B = A(1:end-1)
B =
  2  4  2  4  2  6
