%! @sp 1
%! Private method of the dynSeries class.
%! @sp 1
%! Merge two Dynare time series objects. This method overloads the horizontal concatenation operator, so that
%! two time series objects can be merged using the following syntax
%!
%! a = [b, c];
%! @sp 2
%! @strong{Inputs}
%! @sp 1
%! @table @ @var
%! @item b
%! Dynare time series object, instantiated by @ref{dynSeries}.
%! @item c
%! Dynare time series object, instantiated by @ref{dynSeries}.
%! @end table
%! @sp 2
%! @strong{Outputs}
%! @sp 1
%! @table @var
%! @item a
%! Dynare time series object.
%! @end table
%! @sp 2
%! @strong{This function is called by:}
%! @ref{descriptive_statistics}
%!
%! @strong{This function calls:}
%! @ref{dynSeries}
%!
%! @strong{Remark 1.} It is assumed that the two time series objects have the same frequencies. The two time series objects can cover
%! different time ranges.
