Paolo,
mat = Array[x, {4, 4}]
To extract the 3rd column as a vector just use...
Part[mat, All, 3]
If you are a new user you will probably save yourself some time by reading
through the first two sections of the book and becoming familiar with the
various Mathematica commands that are available. I know, there are a lot of
them so it isn't easy at first.
