function v = horzcat(v1,v2)% Concatenate two vertices objects %% Syntax:%   "vtcs = horzcat(v1,v2)"%%   "vtcs = [v1 v2]"%% Description:%   "horzcat(v1,v2)" returns a vertices object containing the points from%   "v1" with the points from "v2" appended.  "v2" can be passed as a%   list of points, which will first be converted to a vertices object then%   added to "v1".%% Examples:%   Given a vertices object, "v1" representing a square in the x3 = 0%   plane with corners at (x1,x2) pairs (2,1), (2,3), (4,3), and (4,1), %%%%   "v2 = [%%   "2 2 4 4"%%   "1 3 3 1"%%   "2 2 2 2];"%%   "vtcs = horzcat(v1,v2)"%%%%   results in "vcts" a vertices object representing a cube with corners%   at (x1,x2,x3) triples (2,1,0), (2,3,0), (4,3,0), (4,1,0), (2,1,2),%   (2,3,2), (4,3,2), and (4,1,2).%% See Also:%   verticesif ~isa(v2,'vertices')  v2 = vertices(v2);endif isempty(v1) || isempty(v2) || (dim(v1) ~= dim(v2))  disp('VERTICES/OR: different dimensions given')  returnendv = vertices([v1.list v2.list]);
