On second thought I may understand what you are after. Do you view the
two projections themselves as vectors? You won't get a matrix in this
way but you can plot corresponding pairs in a 2D plot and thereby you
will get a "matrix". (When you connect all individual points according
to its time relationship you will obviously get the trajectory projected
down to two dimensions only.) That is what some people do in their
publications.
