It gives you the first column of the array u.
If u is a row vector, that is the 1st element.
if u is a column vector, that is the entire vector.
If you want to transform a row vector into a column, see u', transpose(u), or u(:).

I have also come across the following notation x(:)? Do you know what it means?
