function out = horzcat(varargin)
%HORZCAT Horizontal concatenation of timer objects.
%
%    [A B] is the horizontal concatenation of timer objects A and B.  A and B
%    must have the same number of rows.  [A,B] is the same thing.  Any
%    number of timer objects can be concatenated within one pair of brackets.
%    Only timer objects can be concatenated together.

% 
%    C = HORZCAT(A,B) is called for the syntax '[A  B]'.
% 
%    See also TIMER/VERTCAT.
