Accessing the deeper components of a cell array

Supposing I have an Nx1 cell array, in which each cell contains a 3x1 vector - how do I extract the third component of each vector in the cell array?

i.e. I need something like: cellarray{:,1}(3,1)

which doesn't work.

I realize this is basic but I've been messing around for a while and couldn't come up with a solution

You don't have a choice but use a loop or cellfun (which is a loop in effect):

cellfun(@(v) v(3), yourcellarray)

will return a vector of the 3rd element of each cell.
