%H2E Homogeneous to Euclidean
%
% E = H2E(H) is the Euclidean representation of a set of homogeneous points H.
%
% In the Toolbox points are represented as by Euclidean coordinates which are
% the columns of a matrix E, and the number of rows is either 2 or 3 to
% represent 2- or 3-dimensional points. Euclidean representation decreases
% the dimension of each point by one.
%
% See also E2H.
