Array that grows as elements are defined to belong to it?

So, I am trying to write a function for finding the convex hull of a set of points.
I'm defining an array "H" to be the set of all points in the two-dimensional convex hull.. and would like to have the size of this array increase as I add pairs of points to it. Is there an elegant way to do this?
I am currently defining 'H=zeros(2,(n(n-1))/2)' .. in anticipation of the 'worst' case scenario, where all n choose 2 pairs of points are in the convex hull, which would necessitate trimming it down at the end. However, this seems pretty crude.

I see, so the answer being to define my arrays for the worst case scenario, if possible.
Thank you for your help.
