concatenate two columns in matlab

Hi there, I want to concatenate two variables from two columns in matrix into one column, for example, I have these variables

A =
1 4 6 3
2 6 9 9
3 7 8 0

I want to join the last two columns to be like this

1 4 63
2 6 99
3 7 80

How to do that? Thanx

Is that a numeric matrix, or a character matrix, or a cell array containing numeric scalars or characters, or a table, or something else?
