% @deftypefn {Function File} {} relativeentropy (@var{p}, @var{q})
%
% Computes the relative entropy between the 2 given pdf's.
% @code{d(@var{p} | @var{q})} is the Kullback-Leiber distance
% between 2 probability, distributions, is relative entropy.
% Not a real measure as its not symmetric. wherever infinity is
% present, we reduce it to zeros
