You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: newline.m
    path of file: ./repos/spm/external/fieldtrip/compat/matlablt2016b
    
    the code of the file until where you have to start completion: function [varargout] = newline(varargin)


    
function [varargout] = newline(varargin)

% NEWLINE Create newline character
%   C = newline creates the character representing a newline.
%   newline is equivalent to char(10) or sprintf('\n').
%
% This is a compatibility function that should only be added to the path on
% MATLAB versions prior to R2016b.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% try to automatically remove incorrect compat folders from the path, see https://github.com/fieldtrip/fieldtrip/issues/899

if isempty(strfind(mfilename('fullpath'), matlabroot))
  % automatic cleanup does not work when FieldTrip is installed inside the MATLAB path, see https://github.com/fieldtrip/fieldtrip/issues/1527
  
  alternatives = which(mfilename, '-all');
  if ~iscell(alternatives)
    % this is needed for octave, see https://github.com/fieldtrip/fieldtrip/pull/1171
    alternatives = {alternatives};
  end
