%! @anchor{horzcat}
%! @sp 1
%! Method of the dseries class.
%! @sp 1
%! This method overloads the vertical concatenation operator, so that
%! two (or more) time series objects containing the same variables
%! can be merged using the following syntax:
%!
%! a = [b; c; d];
%! @sp 2
%! @strong{Inputs}
%! @sp 1
%! @table @ @var
%! @item b
%! Dynare time series object, instantiated by @ref{dseries}.
%! @item c
%! Dynare time series object, instantiated by @ref{dseries}.
%! @end table
%! @sp 2
%! @strong{Outputs}
%! @sp 1
%! @table @var
%! @item a
%! Dynare time series object.
%! @end table
%! @end deftypefn
